I can't find any documentation online but we had a memo that every Wednesday going forward you can save 10% with a (free) Rewards R Us card. This means it won't stack on any other sale and probably not with a price match, though possibly with some coupons.
There was no end date so it's probably for a while, at least a few weeks or maybe the summer. Could even be permanent. They can sign you up at a register when you check out if you don't have one.
Not too amazing, but a nice option if you want something brand new and don't have GCU. I work in a Michigan store but it didn't sound regional at all.
I would expect it to show up here, but only if it's permanent.
