Went to order RS Regulate BM-1 today and USPS is not an option in check out anymore. Did Primary Arms drop them? I don't really want to pay $13+ to ship a 1oz item.
UPDATE!!!
I reached out to Primary Arms on Facebook messenger, and they responded: "Hello, we still offer USPS as a shipping service. Some customers have reported issues with not having all shipping options available, if you haven't already you can try to refresh the web page as it may be due to an error in browser cache. We can also do a manual adjustment on an order if needed if you choose "in-store pick up" and get us your order number, we can set it to USPS service for you."
So it seems like a glitch. I tried a different browser so browser cache wouldn't be the issue and it still wasn't there. So if you want USPS then just select In Store and contact them to adjust the order.
