| Web and stores share drop stock | Shared pool with normal sync, oversold | Fixed allocation per channel | A fixed allocation removes the dependency on sync speed during the critical minutes. |
| Carts filling with unpaid holds | Sold out shown while units sit in carts | Stock committed at payment or short hold | Test the platform’s actual behaviour with your configuration, because defaults differ. |
| One buyer, ten email addresses | All ten orders shipped | Matched by address, card and device, held | Publish the rule in advance so cancellations are expected rather than disputed. |
| Automated buying software | Bots take most of the stock | Mitigated at checkout, cleaned up after | No protection is complete. Combine platform protection with post drop review. |
| Site slows under load | Apps and scripts time out, checkout fails | Queue plus non essential scripts disabled | The core platform usually copes. Added components are the usual weak point. |
| Release by draw | Spreadsheet of entries picked by hand | Validated entries, random selection, purchase links | Check whether the draw is a trade promotion lottery needing a permit in any state or territory. |
| In store release with a queue | Store sells beyond its allocation | POS limited to the store allocation | Store staff need the same purchase limit rules as the website. |
| Cancelled orders free up units | Units drift back into general stock | Offered to the reserve list or held | Decide in advance what happens to recovered units so staff are not improvising. |
