A couple of days ago, I put 2 shirts into the cart at RBG. One was 19.99, the other was 14.99. I wasn't done shopping, but I had to go. So I opened it up the next day, and the shirts were now 23.52 and 17.64 or whatever, with line item notes saying, with the discount, 19.99 and 14.99. The discount is a Masters promo, 15% off a $150 order.
So it appears to me that they simply jacked up the prices to coincide with the promo. That doesn't seem very cool.
I'm going to wait it out and see what happens to the prices after the discount expires on 4/15.
