DZC returned $8,200 of this merchandise to the manufacturer for credit on its account. DZC then sold $40,000 of the remaining goods at a selling price of $66,600. DZC records sales returns as they occur and then records estimated additional returns at year-end. During the year, customers returned goods and were issued gift cards equal in amount to the initial selling price of $7,000.
