American Girl is having a Pop-Up Sale in St Louis today through August 14!
I saw on Instagram (credit to @pinkloverag) some prices and what they had. They have American Girl merchandise from Costco, Toys R Us, and the outlet. There's also some overstock that didn't make it to MCM, including Truly Me dolls.
Truly Me dolls and Bitty Baby Costco sets are $98, and you can't use AG Rewards coupons. In my opinion, I don't think this is a good deal.
