eBay September Seller Update: Bundle Discounts Launch on US and UK Sites, Parallel Rollouts of Auto Parts Fitment Tool and High-Value Collectibles Authentication

On September 11, eBay released its September seller update, rolling out new features and initiatives across three core focus areas: multi-item conversion, auto parts fitment accuracy, and high-value collectible authenticity verification.

**Bundle Discounts Launch on US and UK Marketplaces**

The Bundle Discounts feature has officially launched on eBay’s U.S. and U.K. sites, allowing sellers to set tiered discount levels for purchases of 2 items, 3 items, and 4 or more items respectively. Discount offers will be automatically displayed on product listing pages and in the shopping cart, with pricing calculated automatically by the system at checkout. The bundle discount can be stacked with site-wide promotions, but cannot be used in conjunction with seller coupons or order-level discounts. In the event of a partial return, the refund amount will be recalculated based on the actual number of items retained by the buyer.

**UK Auto Parts Category to Roll Out Fitment Plus Auto**

Effective September 15, 2026, eBay’s U.K. site will implement the Fitment Plus Auto feature across its auto parts fitment categories, excluding tires and wheels.
