Sideline Corp. sold 220,000 units of a new product, "Shazam," to Singleton Outlet Inc. for $7.00 each on account. It cost $3.00 to manufacture each unit of Shazam. Sideline sent Singleton Outlet 310,000 point-of-purchase coupons that entitled purchasers of Shazam to a $1.50 discount off Singleton Outlet's retail price. Sideline estimated that 30% of the 310,000 coupons, which were valid from August 1-31, would be redeemed. In August, Singleton Outlet redeemed 88,000 coupons. In early September, Singleton Outlet invoiced Sideline for reimbursement for the coupons redeemed. Sideline employs a perpetual inventory system.
