From a customer e-mail:
You mentioned a discount store-wide and then you also mentioned that the in-house specials will be honored throughout the weekend. Does that mean that BOTH discount codes can be used together?
Though we often run sales concurrently, our web store software will not allow you to use more than one coupon code during the course of a single transaction.
We recommend selecting the one that saves you the most money! :)
Our system only accepts the last coupon entered. Coupon codes cannot be combined.
