I have never wasted my time with these stupid stores and their gimmicks that "save you money".
I do not have a smart phone so they can't track me if I ever got to a mall. I avoid the nix box stores with a passion.

I have 1 credit card from a major credit card company. I get my points and can easily keep track of my spending.
If I buy so etching I pay it off as soon as it hits my credit card. If a store asks for my number I give the the number of the time 860-524-8123 in ct.

Or if they ask for a cell number I tell them I don't have one.

Sadly most people are so stupid they have no idea what they are signing. I watch people at the register talk on the cell phone and completely ignore the cashier. For all they know you could put anything in front of their face and they will sign it.

Remember the store does not care 1 iota about the customer. They care about how to separate the customer from their money and will lie, cheat and mislead you to do it.

So "LET THE BUYER BEWARE". If you are not vigilant you can't blame the store..only yourself.
