A lot of stores are starting to make clients pay them (and do not communicate most of the time, so check your receipts). This plus the forced tips and fees in restaurants. It is probably time to force any seller to show the real price not the tax and fee free one.
I'm fine if there is a cash discount (some places do that and that's much more respectful of the cliets as they usually advertise for it).
edit: clarify my last sentence
