I have to say it sounds like all these comments mentioned about,Swoopo.com are from people that have not won any of the items they were bidding on.
I have, I won an IPOD TOUCH 3rdGen64G for 67.00 and paid 48.00 dollars for the bids, 12.50 for shipping, you do the math and see that I paid 127.50 thats cheaper than Best By 379.00+.
And received it in 13 days they said 14 I love and use it daily, also I was referred by two people from Craig's list.
They win all the time and resell there items for more on Craig's List.
I wait and start bidding on Auctions when it is almost over and WIN, and when I don't' I don't whine about it' Because I play for the fun of it, don't pay and play if your afraid to lose.
