Would have made too much sense to build the site and then start talking with suppliers about deals and rates I guess. It's nobody's fault but your own. "I had to make the goal for Q1 to keep the prices so I launched before it was ready" is not a valid excuse when you should have never been talking to suppliers in the first place without a functional system for your customers to use. Nobody with any sense should be going out of their way to support what is essentially an Amazon cargo cult.
You seem to be more mad than the situation warrants. People go out of their way to support things they believe in all the time. From buying local and organic produce to registering on some web forum about a digital currency. While you are correct that things should of been more polished website you can't really get super mad at them for trying and mad at people who are trying to actively support people who are supporting BTC.
I'd be willing to pay a slightly higher cost on items if I was allowed to pay in BTC, it just so happens that thus far everything I've needed from the bitcoinstore has been cheaper than anywhere else.
