PSA doesn't have an email alert system, and they've not been putting much back online here recently. (I check everything multiple times a day) Your best bet is to check the deals deals deals thread, and the comparable ar15.com forum thread. Between those two, you can keep up with just about everything. Only thing is, sometimes it doesn't last more than 10 minutes. Setup to subscribe to those threads, get instant notification, and keep your phone email handy.
