So in short, the product is not immediately available (it's sold out in the Swag shop also) and when it is, it won't be $5 unless you order it direct. And then, if you don't live in the UK, you'll have to pay an assload of shipping.
Where can I buy R-Pi in a B&M store in the USA, so that I can actually get it for $5? And when will it actually be available?
I walked into Micro Center on Black Friday and picked one up for $5. While I was there, I looked around and was quite surprised how competitive Micro Center has become with pricing.
