Once you accumulate your first 100 points, you can choose to redeem them in exchange for an $5 discount code which you may then use at checkout.
There is no limit to the amount of points you can redeem at once. With 1,000 points accumulated, you can redeem them at once for a $50 reduction.
You can also save the code for another day or send it as a gift but that discount cannot be applied to another code simultaneously.
Multiple codes cannot be combined at checkout so redeem your points wisely.
