Always try to buy in bulk, 12ga packages nicely at 250 shells per case. Ammo rarely goes bad and you can always sell it for a profit. When u find it on sale buy more than you think you need because the price will certainly be higher next time your shopping. I keep a stickie on my phone to quickly remind me about ammo prices. If I find ammo for better prices I get some. Earlier this year my prices to beat was RIO 00B for $.38 each. Slugs were .70 each. I know these prices have long gone now since reelection and shootings but the stickie easily tells me if I found a deal or not.
