When the shelf clock starts and which day counts as day one
The clock we see starts on the day a parcel is marked as shelved, not the day the order was paid and not the day the seller posted it. On our own orders the shelving mark and the first QC photo landed on the same day in 23 of 24 parcels (Recorded, window 2026-08-01 to 2026-09-30).
Count in calendar days rather than working days. Whether the warehouse itself counts weekends and bank holidays the same way is something we have not confirmed on a statement, so we treat our own count as an upper bound (Not verified for the warehouse method).
Keeping the two dates apart matters because the domestic leg can take five days in a busy week. An order paid on a Monday can therefore reach the shelf on the following Monday, and a day count started at payment would overstate the stay by a week.
Cross-check the shelving date against the delivery scan into the warehouse. The two usually sit within a day of each other, and a gap of three days or more means the parcel reached the warehouse but was not booked onto a shelf, which is time you can sometimes recover by asking.
Inside the free window: what the 30 recorded days cover
The free window we read on our own order screens runs for 30 calendar days from the shelving mark (Recorded, reviewed 2026-09-04). Inside those 30 days a parcel can sit untouched while you decide, and no storage line appears on the order.
What the window covers is space, not handling. QC photography at £2.50 per item, rehearsal packing and any repack are charged as their own lines whether the parcel stays two days or twenty, so a long stay is only free in the narrow sense of shelf rent.
A parcel held back until a queue window opens still starts its clock when it is shelved. Community posts put the last week of November at five to seven warehouse days, which we mark as Community-reported and not independently verified, and each of those days comes out of the same 30-day window.
Space is the only thing the window covers, and that has a practical consequence: a parcel that sits for 25 days and then needs a repack pays for the repack, not for the wait. Decide early what the parcel should contain and the free window stays free.
The first billed week and how a part week is counted
Once the 30 days are gone the order begins to carry a storage line. We have never seen that line posted on one of our own orders, because every parcel we recorded left inside the window, so the daily figure stays at Not verified on this page rather than being filled with a guess.
The mechanism is the part we can describe. Storage past the free window is treated as spent money: if the order is later cancelled, that line is not returned, in the same way as the service fee and the domestic freight already paid.
Whether a part day is billed as a full day, and whether the meter pauses over a public holiday, are both open questions for us (Not verified). Ask before the window closes rather than after, because the answer changes the arithmetic of holding a parcel.
1. Note the shelving date. 2. Count 30 calendar days forward. 3. Read the order screen on day 25 for any storage line. 4. Decide before day 30 whether to ship, merge or let the item go.
Ask the question before the window closes rather than after. A storage line that appears on an order is far easier to discuss while the parcel is still on the shelf, and the order screen stops being an argument once the parcel has shipped.
Day 30 is the boundary in the count we keep, and how a parcel that ships on day 30 is treated is one of the open questions on this page. Our own parcels all left inside the window, so whether the meter stops at the moment a parcel is marked outbound or at the moment it physically leaves the shelf is Not verified, and the safer assumption is the later of the two.
What a long stay removes from your options
A parcel on the shelf keeps its options longer than most shoppers expect. Size, colour and quantity can still be changed while the order sits in the warehouse, and cancellation remains possible until the parcel is packed, which our own exit-cost notes treat as the last reversible state.
What disappears is flexibility elsewhere. A second order cannot be merged into a parcel that has already shipped, so holding one parcel for three weeks can cost the chance to share a first kilogram band with a later arrival.
Price movement is the quiet risk. The ladder we record was reviewed 12 times since 2026-04-02, and a rung that reads £8.20 at the 1.0 kg step today is only valid until the next review (Recorded, latest 2026-09-25).
A long stay also affects the next order rather than this one. Two parcels held for a merge will both be measured at whatever the ladder says on the day they are packed, and the ladder we record has been reviewed 12 times since 2026-04-02, so a rung quoted in April may not be the rung applied in September.
Shipping a parcel removes one option permanently: it can no longer be merged with anything that arrives later. Holding a 1.0 kg parcel for four days to meet a second one is worth £4.80 on the ladder we record, so a shelf wait is a decision with a price on both sides rather than a delay with no cost (Recorded, 2026-09-25 review).
Clearing the shelf before the fee outgrows the item
Compare the storage exposure with the value of the item. A parcel holding a £9.00 accessory and a £60.00 jacket is carrying two very different risks, and the cheap line is the one to release or return first when the window nears its end.
1. List what is on the shelf with its value. 2. Mark the item with the worst value-to-weight ratio. 3. Ship, merge or release that line first. 4. Record the exit date next to the shelving date.
Merging is often the cheapest exit. Two light parcels merged into one box pay one opening rung instead of two, and on the ladder we keep that single step is worth £1.40 between the 0.5 kg and 1.0 kg tiers (Recorded, 2026-09-25 review).
Keep the storage break-even beside the shelf list. Where a daily charge is unknown, the break-even figure is the useful number: divide the saving a merge would produce by the days you would wait, and compare that with any daily rate you are quoted.
Two cases where paying the fee was the cheaper choice
Case one: a 0.9 kg parcel waited six extra days on the shelf to merge with a second parcel that was still with a seller. Keeping them apart would have cost a second opening rung at £6.80, so the wait was worth it as long as the daily storage charge stayed under about £1.13 a day, which is £6.80 divided by six.
Case two: a jacket waited four days for the matching size to be relisted. The alternative was a separate 1.5 kg parcel at £9.90 plus £1.00 handling, so the wait paid for itself if the daily charge stayed under £2.72 at day four.
Both cases rest on the same break-even sum, and both depend on a daily rate we cannot confirm. Run the division before the window closes, then decide with a number rather than with a feeling about shelf time.
A second break-even is worth running before a long wait: divide the cost of the alternative by the days you would hold. Where the alternative is a second parcel at £6.80 and the wait is five days, the break-even is £1.36 a day, and that figure is the one to compare with any daily rate you are quoted rather than a general sense that storage is expensive.
1. Write down the saving a wait would protect. 2. Divide it by the number of days you would wait. 3. Compare that figure with any daily rate you are quoted. 4. Release the parcel when the quoted rate sits above it.
The data point behind this note
The free storage window we record on our own order screens is 30 calendar days from the shelving mark, and the daily charge after it is Not verified because we have never seen that line posted on an order (Recorded, reviewed 2026-09-04).
Rates last checked 2026-10-02. Where a figure is community-reported we say so; where we could not verify it, we write Not verified instead of estimating.
