Dealfun is absolutely dreadful. I have spent hundreds of dollars purchasing bids on this site, and have not won any auctions at all (with the exception of the first "gimme" auction they set up when you first join; you get 10 bids). I follow their advice, use my bids wisely, do what I see other people doing, yet still haven't won a thing.
The site warns you not to bother going up against what they call "prestige bidders" (are these straw bidders or people with issues?)… I assure you that anything worth winning will be won by one of these people.
It's much like a bait and switch… they are happy to show you the iPad they sold for $42.00 (did the site go down or something?), and the PS3 that sold for $12.00, but don't ever bother to hope that you will win an item at these prices.
While some say to wait until just a couple of people are bidding, then swoop in and start bidding at the close, I offer this: if someone has spent hours trying to win an item it's not right to jump in right at the end. I've never done it to other people, and don't appreciate it when someone does it to me. It's really annoying when an auction is prolonged unnecessarily by someone who bounces in and starts bidding like a fool; it's an invitation for more people to come in and prolong the auction indefinitely. That is exactly what happens at Dealfun. Auctions take far too long to finish, meanwhile the site is raking in more and more money.
It seems to me that a handfull of fools has come in to Dealfun and taken over; their prices are inflated for a penny auction and there are a few screen names that you will see winning the best items consistently. I have a feeling that they buy from Dealfun and sell on EBay.
Dealfun also touts that they will apply your bids (not bonus bids, but purchased bids) to the cost of an item. When I started to lose money on the site, I decided that I may as well take advantage of this, and started to order items in hopes of selling some elsewhere to at least break even (cover the loss I incurred buying bids). To date I have not received anything that I have paid for. Customer service won't talk, and the items are in what seems to be a perpetual "processing" status.
Dealfun is NOT the place to go!
