I have 2 supply banks. One charges $3 per box and the other charges $4.50 for as many as I want. The $3 boxes produce a lot more than the other bank so I use them the most.
I also have to pay to dump half the time. When the coin counters at Capital One are working, there is no fee. Most of the time they are down or the bin is full and Brinks hasn't brought them an empty one. Wells Fargo charges me 1% to dump. Despite all the fees, I am still pulling enough silver to pay for $4 gas. Cheers, Jim
