eBay is offering all eBay sellers an average of 30% off domestic USPS shipping
when sellers use eBay labels
. (It's the same discount offered to eBay's Titanium PowerSellers, Platinum PowerSellers, and Top Rated Sellers.) That's a savings of at least $2 with a priority mail medium flat rate box. It's also very possible that these lower shipping costs may lead to price breaks for shoppers, as well. Deal ends December 31.
