Free: Contests & Raffles.
Maybe won't help you if you need it today, but I buy all of my ammo through rogers sporting goods online. They have great prices and usually have what you want if you buy early enough in the season. Free shipping to your door. If I buy on monday, it is usually delivered to me by thursday.
i wonder how often rogers gets restocked, their inventory has shrunk since this time last year and everything that's gone "out of stock" has never come back. i did pick up a case of 2 3/4 nitro mags for 100 bucks from them this summer, they go for $20+ a box locally. can't beat that especially with free shipping.
Just bought the special this weekend from Rodgers a 250pack of 12g 2 3/4 #2 for $89 free shipping!
