OP - people go on auction sites to get a bargain.
Very often they end up paying over the odds because they get caught up in excitement and forget the value of what they are bidding on - that my friend is where the big bucks are made.
You don't even offer that as the product has a pre-determined price, no excitement, just slowly parting with cash for nothing, I would ask for a refund long before a week when my bid was lost. When your punters realise that you have nothing.
What the....
Ok here is a story board of eBay versus ezeepeeze,
eBay - a punter logs in looking for an xbox, they see that there are 5 on there at the moment all priced between £150 and £200 buy it now and another 2 which are private sellers listing for auction, these private sellers have not set a reserve and NO ONE knows what the end price is going to be, it could be £5 or £123 or £300 who knows but they bid on this SECOND HAND xbox in the hope it'll actually work.
The item will most probably go for around £130 as that'd be acceptable in the current market and people would just refuse to part with any more cash, add £10 for shipping, you now have a second hand xbox on it's way (maybe) if the seller is legit for £140. It may or may not ever turn up, let alone work.
ezeepeeze - a punter logs in looking for an xbox, they see 5 available all of which are priced at £100, the current bids of these xbox's are £5, £22, £90, £92 and £17 (so in turn the next possible bids are £6, 24, £91, £93 and £18)
The punter makes a first bid of £92 knowing that as soon as he/she reaches £100, that brand new xbox with warranty will be shipped garaunteed.
Some one else bids on the £6 forcing it up to £7 (£8 following) the punter bids the £8, ezeepeeze recognises that they have already got £92 in the bank adds the £8 = £100. done! Everyone else continues bidding on what ever they like and that punter gets what they want.
Now tell me that you don't prefer the cheaper quicker brand new product in a box that CAN be returned if faulty!
Remember that for the bids to be at 6 24 92 93 and 18 ezeepeeze would have already collected about £10k. I win and so does everyone else.
