A common complaint about QuiBids.com is that the user base is too large, resulting in very reduced chances of winning an auction. Because the service costs money simply to bid, a large number of users continually lose money on auctions without winning.
Some users on ConsumerAffairs.com suspect that QuiBids employees participate in the auctions. However, there is no proof of this claim, as of April 2015. Because the service costs money to bid regardless of whether the user wins an auction, QuiBids has an incentive to continually bid against its customers.
Additionally, numerous users complain about unclear billing policies. In some cases, QuiBids has offered a free trial membership while nevertheless asking for credit card information. One user on ConsumerAffairs.com notes that QuiBids charged $60 for the placement of bids without explicitly indicating that the placement of bids was not free.
Another common complaint about QuiBids centers on the site's use of fake Craigslist ads to lure in potential customers. The site posts ads on Craigslist for products at unreasonably low prices. When interested customers email about the product, they are informed it is no longer available, but that they could enter an auction for an identical product through QuiBids.
