I've used AmmoSeek a few times, mainly when I was searching for 9mm and .223 ammo. It definitely saved me some time by compiling prices from different retailers, which is nice to see all in one place. Most of the listings seemed accurate, but I did notice that sometimes, the prices would change quickly, so it's a good idea to double-check before you hit the checkout button. I haven't run into any sketchy sellers myself, but I always read some reviews on the retailer before buying, just to be safe. Overall, it's a handy tool, just keep your wits about you and compare a bit before committing to a purchase.
