I don't know if this really belongs here (I'm considering this as a "resource"), but I recently bought some things from my local Guitar Center and discovered that they have a good selection of various types of equipment AND they will price match any item, and then take off an extra 10% of the discount. (You see $200 item in the store, find it on Amazon for $150, they take $50 off, plus 10% of $50, making it come out to $145)
I ended saving almost $100 dollars on a $340 purchase (would have been $440 normally) thanks to this price matching and one other deal they had in store. I don't know if this is common knowledge, but I figured I might as well share it since I personally much prefer to physically buy items rather than order them in the mail.
