$100 gift card to Southwest Airlines are on sale right now on Ebay for only $90. Limited quantities are available so if this is something that you can use, make sure you hurry and buy it.

From time to time, places like Target will discount an Ebay gift card for $5 off $100 so you can effectively save even more when these type of deals pop up by stacking an Ebay gift card with a deal like this for a Southwest gift card.

Personally I always watch for a Jiffy Lube $50 gift card for $40 sale on Ebay and snatch those up as that is where I alway get my oil changed.
