In my humble opinion, I think you are going to be in a catch 22 situation.
1) If you are unable to procure enough capital to get a sizable amount of GPU cards, you'll run out of cards soon and will then be out of stock. And you'll have all the whiners complain etc.
2) On the other hand say you do get a sizable amount of GPUs you willl not be able to keep up with demand just like other retailers. Part of the high prices is to keep the demand in check. I think even by selling at Newegg prices is still a plus since peeps can just mine and buy the cards. Which I think in itself is a big plus. So I would only undercut Newegg prices by say 10 - 20 %. Anything more and you'll run into issues.
3) Say you become successful, you will need to increase your operation, that means more inventory space, full time employees etc and will you not be competitive enough with your prices. Then again if you sell at Newegg prices with GPU coins in itself would be a plus.
I would also recommend securing the newly released R7 265 since they do will become scarce. Basically any mining gear that can be purchased through GPU coins will be a big plus to the community.
Please don't be offended by my comments. I am by no means in retail so I could be completely off on my assumptions.
1. While the business start is definitely an issue, we are hoping the IPO will gain traction. We just submitted our credit application to the distributor and if that goes through we get any items we want on a 20 day loan so we can have a sizable stock ready for the grand opening.
2. The prices we are selling at will still pull a sizable profit for ourselves, the issue is that it takes a week to receive shipments. If we are able to keep a large stock to begin with, then selling and buying should flow easily enough.
3. There are are two people working at the home base and any on-line retailer can operate out of home. If the business explodes to that level then we can move to a house with a large, secure detached garage. In all honesty that would really require sales in excess of 3000 units a month, which would be a super long shot.
Distributors currently don't have any R7 265's for sale, but we'll keep an eye out for when they do.
