I don't order food from Amazon at all because I don't trust them not to send something counterfeit or expired. It's just not worth the risk/hassle, and a lot of the time they're not the best price anyway.

I'm also extremely cautious about electronics, but there are still certain categories (such as memory cards) that I won't even consider. Usually the only benefit from Amazon vs anywhere else is shipping, and saving $shipping is simply not worth the risk of using a fake card.

This is a step in the right direction to fixing the problem, but I'm not sure I'd trust anything -- even stuff sold by Amazon itself -- so long as they co-mingle inventory.
