TL;DR: UPS sucks.
Bought 400 FMJ rounds of 5.56 with a free ammo can. Price was decent for post-2020.
My issue isn't really with Green Country themselves, but UPS, who actually delivered it, though GCA does have some responsibility for only shipping with UPS. Well, they didn't deliver it. It was lost for a day or so. I got a notification saying it was delivered and left at the door. It wasn't there when I got home from work. I later got another notification that it was delivered to a UPS handling facility because they couldn't deliver it to my home (They could, but it wasn't even attempted). Fine, whatever. I went to the UPS facility on the same day only to find out their computer systems were down so they couldn't even have accepted a package. So I filed a lost package complaint. Sure enough, the next day the package reappears and is delivered to the same facility, successfully this time, and I got my hands on it later that day.
I don't plan on dealing with GCA again purely because of UPS's incompetence.
Received 50 JHP rounds for my .357 magnum only a few days after ordering. AND it was during a historic snow storm in my area. Bullets I received are good quality and you can't beat the price right now at a time JHP are difficult to find an normally very expensive. Also, the shipping price was very reasonable. Will definitely order from GCA again!
