I may be an evil genius(how to screw the customers!)

This is why I should be at Grumbel's Corporate...

*Store's return policy-you can either have cash or store credit.Store credit is more to make it more appealing*
*If you accept,you get given a card which will show how much you have left.*
*You sign to acknowledge you have received your Grumbel's 'Store Credit Card'
*Congratulations,you have now signed for the 'Grumbel's Store' Credit Card.

And that's how to get your people signed up for the store credit card without them realizing at all....
It wouldn't work....surely?

As most people would never read the contract, it would work until someone exposes it, Hopefully no one would find grounds for a lawsuit.

You are borderline "Fraud in the Induction". As long as nothing you verbally say contradicts what the contract says, you should be fine.

With the usual IANAL caveat this would probably fail the "Reasonable Person" test. https://en.wikipedia.org/wiki/The_ma...lapham_omnibus
