Groupon Deal for a $15 Ebay Gift Card that only costs $7! I though I would post it quick in case you didn't hear about it yet, since it's still available through 3/31/11.
Not only is this over 50% savings, but it also works on shipping and can be used on multiple Ebay orders. Limit 1 per person. Limit 1 per order. Valid only on eBay.com in the U.S. and you must have a registered eBay and PayPal account to use your Groupon.
Thanks Money Saving Mom!
