I got a killer deal on Black Friday. Dicks was running their buy one get one 50% off deal (max 6 boxes, total). I went in to the store, and their prices were higher even after the discount than Walmart's normal prices!
Then I took the ad to Walmart and asked if they'd honor it. Walked out with 6 boxes of Winchester -- 2 boxes of the 100-rd 40 S&W for $42 (regular $56) and 4 boxes of 100-rd 9mm for $60 (regular $80). That works out to 21 and 15 cents per round!!! Cheap as I've found. Just wish I'd gotten to a couple more Walmarts before the sale ended (didn't realize the ad was only valid till 2pm).
Still, for $18 / box, I wouldn't have minded a little more from Academy. What I do with Academy (not Dicks or Sports Authority, cause their prices are just way too high) is buy gift cards off Craigslist for about 25% under value.... It's my way of getting the discount, since the 25% off coupons never seem to include ammo.
