Membership loyalty cards typically gate "yellow tag" pricing. Some yellow tags are for bulk purchase discounts but some are just "discounted prices". The FTC says that it's deceptive pricing to advertise a sale while raising prices, but since yellow tags are membership pricing, not a discount, it's defensible to raise prices with the original price as a yellow tag rate, available only to members. Yellow tags are not always promotional prices.
