When a store clerk refuses to charge me the digital price, even though I'm disconnected, I simply leave the item(s) at the register and make the store return them to the shelf, freezer, or whatever. I sometimes do this repeatedly to get my point across. This takes up time for the employees which costs the store money. The clerks don't care; they're being paid by the hour. When stores realize their policies are costing them money and customers, they'll eventually get the picture. I've been able to "condition" a few stores to give me the digital price without me even asking. Lesson: Don't mess with old people!
