Just going off first glance, you shouldn't trust that site.

 - They're still using the old image for the 5GH/s Jalapeno and 25 GH/s ASIC. You'd think they'd keep up the product stats and details if it was all they sold.

 - They have a single, unchanging bitcoin address right below their "bitcoins only" logo. No reason is given as to why a commercial site would have a static address just sitting there, like they expect donations or something.

 - The store itself has no logo or even a name, apparently (unless it's just "w-stores.") How'd you even hear about this site?

 - They have 3 Jalapenos in stock, but it's going to take 12-22 days to ship? And for a bitcoin value of under $250 USD? Riiiiiiight.
