We offer a discount (say 10%) on your first purchase when you open a credit card. We are proposing to have a sign at the register that says "Get a discount on your first purchase when you open a credit card" - with no disclosures on it. We would also have a leaflet with all of the required reg Z disclosures (APR, FC, etc...) with all the details. Does anyone see anything requiring disclosure for the posted sign? Thanks.
