No provision of a retail installment contract, retail charge agreement, or lender credit card agreement is valid by which the buyer agrees not to assert against the seller or against an assignee a claim or defense arising out of the sale, or by which the buyer agrees to submit to suit in a county other than the county where the buyer signed the contract or where the buyer resides or has his principal place of business.
