I don't think they charged tax. I can't find my receipt. I did order only one case.
For years we have been getting ammo so cheap, I find that even 10 bucks a box is hard for me to swallow sometimes. I remember back about 7 years ago I bought Russian 9mm for $6.00 a box. The .45acp was $10.00
7.62x 39....$3.00
and prices seem to be returning to normal.... i predict one more round of ammo shortages as it become available more people will buy again... predicting they will level out by the end of the summer.
