PM me your address Mr Drums and I will send you some for free, I have lots. Just a heads up; Walmart puts out caps in July for $5 and change a tin, they don't last long, it is my understanding that more people steal them than pay for them. In July I walk by the M/L stuff every time I go in the store, on one trip they were on the rack, I picked up 3 tins and left the remaining tins on the rack for someone else. We have three Walmart's in town, I don't shoot percussion much so I didn't go to the other stores and get a few more. I do keep a stock for a SHTF scenario, caps, flints and 23# of powder.
Academy has them as well before hunting season, theirs's are $13 and change a tin, they do price matching so if you have proof of Walmart's price, they will sell you some at the $5 price Walmart charges.
