Don't Get Burned At The Cash Register

People make mistakes. Computers make mistakes. When shopping, you should always know your purchase total before going to the cash register.....

Yes, you should know within $1 what your tab, bill, check, order, etc. will be before the cashier or waiter tells you. I notice that 1 out of 10 times there is a mistake in the total I am told to pay versus the actual total. And it is usually not in my favor!! Protect yourself and know your money!!

Does anybody practice this money-saving habit?
