Your signature on a contract indicates that you have read it and understand its terms and conditions, even if you haven't read it or have only partially read it. The written contract usually holds, unless satisfactory proof is available that you were induced to sign the contract through false or fraudulent representations, and this is always difficult to prove. For your own peace of mind request all oral representations be inserted in the contract before you sign it. A contract is binding even if signed on Sunday or Holiday, or if its' signed to get rid of a persistent salesman. Never sign a contract on the assumption that it will not be binding.
Some guarantees are full of loopholes through which the guarantee can be evaded.
It is of extreme importance to know and understand the limitations and terms of guarantees because the word itself, when used alone, means little and is ambiguous. It doesn't have to mean satisfaction or your money back, and can sometimes actually reduce the seller's responsibility. Most contracts provide that even though an article is repossessed or returned willingly, the customer is obligated for the difference between the amount obtained by the seller in the second sale and the balance due on the contract.
