I found all the single ponies at a Walmart in Puyallup, WA, the week before Christmas. And this morning I found these sets at a Target in Tacoma, Wa.
Terrible Cell phone Pics Ahoy!
Fashion rarity was $12.99, Princess Celestia was $19.99. The Carriage was $10.99 and the others did not have price tags.
Fingers crossed Monster High is restocked soon.
