Has anyone ever bought anything from Jackthreads?
http://www.jackthreads.com/invite/nouveauk It's kind of an invite-based online store that sells apparel, hats, sunglasses, and other clothing items. I signed up to it recently, and it appears that they sell a large variety of both popular and obscure brands of clothing, marked down by up to 80%. The merchandise switches up every couple days, so it's like a constant cycling of new products that, alarmingly quickly, get sold out and replaced.
You can't see the things they have fully unless you make an account. Luckily, it doesn't take long. The initial webpage looks a little too advertisment-y for my taste, but once you log in it's not as bad.
I don't really know what style of clothing the average B12er likes (can a B12er even be quantified into an average?), but the site so far seems to have a variety. Like the funny T-shirts, or high quality shirts/jeans, and also some hiphop-style hoodies and beanies. How they manage to sell brandname stuff at half-off, though, I've no idea.
And, uh, though it's ridiculously unlikely, apparently if you sign up before March 15 (it started Feb 17), you get entered into a drawing for an iPad, and they'll contact the winner via email. A chance to win a giant iTouch. Hahah.
