I've got a bushel basket of 30 round AR-15 magazines, and almost as many 20 rounders. Yesterday, I bought 20 more Colt and Magpul 30 rounders. And a bunch of floorplates, springs and followers. They're still relatively cheap, and readily available. Next year, they may not be available at all, or they may double in price. Remember what your Soutmaster taught you: "Be prepared."
