I stopped by the local Microcenter (which is, incidentally, has a nice assortment of hobby-oriented electronics items for sale) and they beat Amazon's price on a Samsung EVO SSD by over $20. Since they price match, I got a $3 discount on one of the other pieces of hardware I bought that day.
All in all, the time I spent driving there likely make the savings irrelevant, but I was surprised that they were so much more aggressive on the SSD pricing.
