Bass Pro Shops has changed the way they sell ammunition, preferring giving stock to their own stores rather than ship direct to customers. Almost all of the previously cheap ammunition is now available exclusively in-store. This change renders this tool moot - for now.
I'm evaluating options, including: monitoring other stores, providing in-store stock alerts, etc. I'm also going to school full-time, so it'll be slow.
Do you have feedback, or (even better) great ideas for an ammo-finding tool? DM me on Reddit.
