Do coupons work with all Makers?

Do coupons work with all Makers?

Makers have the option to opt-in to the marketplace coupons and promotions. Coupons issued by the marketplace may not be accepted by our Makers.

Makers may also issue their own coupon codes for discounts on their own products. When using a coupon code issued by a Maker, the code will only work on that Maker's products only.
