I don’t do it nor do I “suggest” it (or buying coupons off eBay) but some of you may be interested in the rules and restrictions for selling coupons on eBay.

What are some of guidelines to selling coupons on eBay?

• ALLOWED
• Valid, unexpired coupons.

• RESTRICTED (these are allowed but there are limits or restrcitons)
• Bulk coupon sales: In a single listing, sellers cannot list more than 100 total coupons, 20 identical coupons, or 5 coupon inserts (like those that come with a newspaper). Make sure you clearly state in your description how many coupons you’re selling. If we can’t tell how many coupons are offered, the listing violates our policy.
• Coupons for “free” products: You can only list 2 coupons for free products, with no purchase required, per listing.
• Coupons printed off the Internet: You can’t list more than 2 printed Internet coupons per listing.
• Expired or used coupons: You can’t list recently expired coupons or used coupons on eBay because they could be used to commit fraud. Collectible coupons that clearly can’t be redeemed may be allowed.

• NOT ALLOWED (you cannot sell these types of coupons)
• Electronic “scanned” coupons: All coupons sold through eBay must be physical coupons printed on paper, not coupons that can be sent electronically to the buyer to be printed. Also, to reduce the potential for coupon fraud, we ask sellers not to include unaltered scans of coupons in their listings that could be copied, printed, and redeemed in stores. (Note: The sale of scanned or photocopied coupons may violate federal copyright laws, and sellers of unlawful items like these could face prosecution under federal law. eBay doesn’t allow the sale of these kinds of coupons.)
• Coupons for recalled items: Coupons for items that have been recalled by the manufacturer can’t be listed on eBay.
• Recalled coupons: Coupons that have been recalled by the manufacturer can’t be listed on eBay.
