I regularly offer discount coupons for our products. These coupons are published in our newsletters or sent as an already discounted checkout link. Here is our policy in regards to accepting discount coupons: Discount coupons are only valid for new purchases, and the coupon code must be entered into the Coupon box at the time of purchase to obtain the discount. Each discount coupon has a published start date and expiration date: The discount cannot be applied to purchases that happened before the coupon start date. The discount cannot be applied to purchases that happened on/after the coupon expiration date. Customers who purchase a product for which a discount coupon is active on the day of the purchase have 3 days to write to support and ask to receive the discount. The discount cannot be granted if the customer writes to us later than 3 days after the purchase.
