Thanks for this OP!
I've noticed that lately I've been buying more from Newegg and Best Buy lately, rather than Amazon. I guess that's a good thing as come September 15th, everyone living in California will have to pay tax on Amazon purchases.
That, and the fact Newegg and Best Buy are beating Amazon with prices recently, I think it's going to be a long time before I buy from Amazon again. That is unless, they actually start acting competitive again.
