1. Misunderstanding the Shipping Estimate
The cost shown at order time is a very rough estimate based on item weight. The actual bill is based on packed or volumetric weight. Difference: 10–30% in either direction. Budget 10% above the initial estimate as a baseline; run parcel rehearsal for big orders.
2. Ignoring QC Details
Auto-approving feels fast. It's also how you end up with the wrong size, mismatched color, or visible defects you didn't ask for. Spending 60 seconds per item on QC review catches 80% of avoidable returns. Specifically: check size tag, look for zoomed-in defects, and confirm color against seller's product page photo.
3. Choosing the Wrong Shipping Line
The two most common errors:
- General line for sensitive items. Logo-heavy or branded goods get flagged at customs on general lines; sensitive lines are worth the extra 20–30%.
- Priority line for non-urgent items. Paying 50% more to save 3–5 days on a casual purchase is a donation to the carrier.
Default rule for first-timers: general line for clean items, sensitive line for logo / brand / electronics. Priority only when you genuinely need speed.
4. Submitting Parcels Too Early
Biggest money-waster. Shipping a single item pays the full per-parcel overhead (carrier fee, minimum weight, etc.). Five separate parcels = ~3x the cost of one consolidated parcel. Use the warehouse as a basket; submit a parcel only when you're ready to ship several items together.
Exception: truly time-critical single items.
5. Misreading Spreadsheet Entries
The Spreadsheet is a directory, not a store. Common misreads:
- Treating Spreadsheet prices as final → they're snapshots; the seller's current price wins.
- Thinking "click to buy on Spreadsheet" works → you have to submit the link through your OOPbuy account.
- Expecting OOPbuy to take responsibility for seller quality → OOPbuy inspects (QC), doesn't guarantee.
5-Day No-Reason Return / Exchange Policy
Most buying mistakes can be reversed within a short window. OOPbuy supports a 5-day no-reason return / exchange service tied to seller policies on third-party platforms.
The 5-day window
Counted from the next full hour after the order status changes to Stored in Warehouse. After 120 hours from that timestamp the no-reason option is gone.
What is eligible
Eligible if all three apply:
- Seller offers no-reason returns (most do; check the listing).
- Item is in resalable condition — original packaging, tags intact (see the Packaging Integrity table).
- Stocked in OOPbuy's warehouse for no more than 5 days.
What is not eligible
- Custom-made products and items with packaging/tags removed at your request.
- Newspapers, periodicals, second-hand items, undergarments, food, adult products.
- Products from outside mainland China (overseas, Hong Kong, Macau).
- Books in bulk (≥ 15) or any items where the original sealed packaging has been opened on categories listed in the integrity table.
Service fees
One free return or exchange per calendar month. Beyond that:
| Action | Fee Components |
|---|---|
| Unconditional return | Shipping to seller + shipping from seller + 5 CNY service fee |
| Unconditional exchange | Shipping to seller + 2x shipping from seller + 5 CNY service fee |
If the seller offered free shipping originally, the first-leg shipping cost is still owed back to the seller on return / exchange. If the issue is the seller's fault (wrong item, quality defect) you do not pay shipping.
How to request
Go to Orders → select order → After-Sales. Pick the reason that matches:
- Don't want any more / wrong purchase / shipping over budget — customer responsible for fees.
- Seller shipped wrong item / quality issue — seller responsible.
- Damaged in domestic transit — logistics responsible.
