I see them all the time at Toys R Us
The Toys R Us near me never has them. If you're still trading cards, I'd recommend buying a few packs to trade. A lot of people are willing to trade 2:1 for the WA because they are unavailable in a lot of areas.
I've been trading cards like Merengue, Stitches, Julian, Beau, Chrissy and Lolly to complete my WA collection.
