Shein Final Checkout Zero-Out

Shein's checkout system experienced a total wipeout on November 22, 2024, just before Black Friday. A final-step price recalculation reduced every cart total to $0.00. The system applied a rounding error that cascaded through every line item, zeroing out balances regardless of cart size.

Bandar's Bounties detected the zero-out at 1:30 AM EST when automated checkout testing showed $0.00 totals on carts worth $50-$500. The alert went out immediately with instructions to load carts and complete checkout.

Members filled carts with clothing, accessories, shoes, and home goods — then watched their totals drop to zero at the final payment step. No promo codes needed. No minimum purchase. Just a broken calculation that made everything free.

Shein's engineering team patched the checkout calculation by 4 AM, but thousands of orders had already processed with $0.00 charges. Remarkably, Shein fulfilled every order. Packages shipped from warehouses worldwide and arrived within their standard 7-15 day window.

Checkout calculation errors are the most dramatic type of glitch — your entire cart becomes free. Bandar's Bounties tests checkout flows continuously to catch these moments.
