I get the promotional e-mails from Botach, and today they were advertising OEM Glock mags for $17.98. I ordered a few and after taxes and shipping they came in at $20.86 per mag. I got a couple of 12-round G26.5 mags, some G19.5 mags, and one G17.5 mag. The G26 mags have the +2 extensions and usually cost more than mags without the extension. Botach isn't a place you'd want to order from if you're in a hurry, but I've always received my orders. In any case, if you need new Glock mags, this is the best price I've seen lately.
