need to watch other users, and especially for those that would never stop bidding. very hard to win against those with unlimited pockets who are really bidding for "fun". strategy is a big deal in penny auctions. i've seen users winning with just a few bids and i've also seen others wasting money.
i have registered with several penny auctions sites and been watching them closely for quite some time now. simply watching auctions can be fun, but when you win it is quite profitable too.
As far as bidrodeo:
Pros:
* very helpful customer service. when i sent them email on saturday night i wasn't expecting an answer till the following monday, honestly. was very pleasantly surprised when they replied within just a few minutes and have solved my problem.
* reliability and responsiveness of the site. wouldn't name other sites here but i use several other penny auction sites, and notice that bidrodeo is one of the more reliable ones. for example on other sites quite often either my timer freezes or you can't even put a bid. didn't have any issues like that with bidrodeo so far.
Cons:
* not enough auctions, I would like to see more auctions both, more variety and just more quantity. may be starting earlier during the day too.
overall give it solid 4 out of 5 as a good site
