eBay also said it is introducing a new listing policy for sales of manufacturer's coupons. Effective Wednesday, the sale of recently expired coupons is not permitted on the site, although collectible coupons that clearly cannot be redeemed may be permitted. Electronic “scanned” coupons are not permitted on eBay. All coupons sold through eBay must be physically delivered to the buyer, and may not be delivered by electronic means for home printing. Bulk coupon sales are not permitted. And Internet home-printed coupons, as well as coupons for “free” products, with no purchase required, are limited to 2 per listing.
