(2) When the contract is received from the retail buyer, the seller shall prepare a written memorandum containing all of the information required by ORS 83.030 to be included in a retail installment contract. In lieu of delivering a copy of the contract to the retail buyer as provided in ORS 83.070, the seller shall deliver to the buyer a copy of such memorandum prior to the due date of the first installment payable under the contract. However, if the catalog or other printed solicitation does not set forth all of the other terms of sales in addition to the cash sale prices, such memorandum shall be delivered to the buyer prior to or at the time of delivery of the goods or services.
