Just thought that maybe they would do that if you went into the store. I just purchased a TV from there for $699 on a Tuesday and noticed online they were selling the same TV at a discount $499 on Sunday and was "1 day only clearance sale" and after showing customer service the ad I had saved the webpage on my phone, I got $212 back.
They do honor price matches, but only from a direct competitor like Walmart, Target, Amazon, Fry's Electronic etc...
Several years ago I used to work at Home Depot as a cashier, and we would offer a price match if you brought in an Ad from Lowe's, Orchards Supplies, Ace Hardwars, but not from a Mom-and-Pop shop (because we didn't directly compete, even though we sold the same items).
