$50 "skycash" coupon shoved into my hand leaving Penn Station this morning
$50 off a winning bid at Skyauction.com
Apparently they have auctions with bids that open at a dollar. It seems prudent to bid $50 once a day until you win something.
I'm not recommending the site - I never used it.
"upon confirmation of your winning bid, enter "skycash coupon" into the comments section of the Fulfillment page.
