I can boxes from about three different banks here in town but bags are a different story. One of the banks rolls all the coins brought in and uses them to keep from paying the armored service so I get mostly customer coins and find some pretty cool stuff. One doesn't take loose coins but will let me buy all the rolls I want the other one has a counter that is free to customers so I dump there and they don't mind since I'm a customer. One bank told me no I couldn't buy the bags because they sent them to the Fed or whoever then they decided I could buy them but had to take them as is meaning if I found foreign or lower denomination coins that sorted wrong I was stuck with them. I didn't mind that as it doesn't happen often anyway. The CU doesn't roll coins and will only sell a few rolls at a time for some reason so I don't fool them. Hope you get this worked out to your advantage and I don't agree with their policy at all customer service should come before a corporate bureaucrat that only looks at the bottom line. I have been in retail either privately or corporately for the last 30 years and the last thing you need is a customer to get upset over a policy that's not going to cost you the farm. If one person gets mad they tell a dozen friends who get mad and if they tell it on the internet then it could be exponential.
Lol. We were doing halves. I was getting $1000 bags for awhile from one branch until I was in there once on an actual banking matter unrelated to our addiction and I saw a guy come in with literally a wagon-full of bags of halves for the counting machine. No wonder there was never any silver in those $1000 bags.
Quite awhile back, I got into a conversation with the cashier of our work cafeteria. She complained that the armored car company cost them $600 per month. Probably double that now. Would not surprise me to find that this change was a result of a call to headquarters from the armored car company, resentful at losing their profits.
