I do something similar. In Firefox, I have all those primer pages bookmarked and in their own folder. When I want to check I right click that folder and choose open all in tabs. They all open and load at the same time so I can check them instantly.TG, if you can, I recommend having your credit card always handy and bookmarking the exact pages at Midway, Brownells, Midsouth, Natchez etc for the items you want. I randomly check those websites anytime the spirit moves me when I'm at a computer, and the times I have successfully ordered primers it was because I discovered they were available via that method before the email notifications even reached me
I bookmarked midway, Midsouth, brownells, natchezss, grafs, etc.
