Hey all! Just wanted to let everyone know that RCSS emailed me back today saying that this does indeed constitute stacking and sent me a copy of their rules along with it. Apparently it falls under:
2.5 A coupon cannot be redeemed against the “free” item in any offer where the customer buys more than one item to get one or more item for free (BOGO deals). Eg. Buy one bag of chips, get a second bag of chips free – a single coupon can be applied to the purchase of the two bags.
