I want to see these in my area. I’m usually a little intimidated buying ammo.
I hit a dirty look from some girly cashier, one time. Other than that, no problems.
Buy online. Buy in quantity if you want to save money.
Even if you boutique buy, a quality place like Midway will probably save you money over a gimmicky vending machine. And no "facial scan" that the machines supposedly do as part of their security theater.
