The Large Print Giveth...
... and the small print taketh away.
Example:
The sign above the soda pop advertised "5 12-PKS. for $10.00" . There was some smaller writing underneath but I figured that was just a notice that I would have to use my card. I picked up a pack of root beer and a pack of ginger ale. When it was totaled at the checkout I noticed that I'd been charged full price. I'd used my card so I asked her what was going on.
She informed me that I had to have a coupon from the local newspaper and the sale didn't start until Saturday. I said, "Forget it then, I don't want it." Then I added, "The large print giveth and the small print taketh away."
I had always wanted to use that line since I had heard it. She cocked her head to one side and looked at me with a puzzled look and then put the 12-packs under the counter.
I looked back at the customer behind me for a response but I was met with a blank stare. Subtle body language told me to move it along you cheap punk.
On my way out I checked the small print under the sign and she was right.

If it seems too good to be true, it probably is.
There is no free lunch.
