While calculating preliminary costs, our operator searches for coupons and available promo codes on the most famous coupon sites. Coupons that you indicate in the comments are also used. Exceptions are made for personal coupons that are registered to an individual through his personal account on the store’s website. If the operator comes across a new coupon that provides better discount for the purchase during the buyout, he will apply it and a smaller amount will be taken from the customer’s balance.
