I used to buy two Federal Bulk-Packs at W-M every month or so. That meant I could shoot one and put one up.
They went up in price from about $15 to about $20 not long ago...and then disappeared. Haven't seen one in any of my local 3-4 W-Ms in the last 3-4 months (North TX, DFW area).
I see a box here and there at local gun shows, selling for from $23 to $35.
Guess I'll shoot up a bit of what I had put up over the last couple years.
