Snow White might be left, but Jessie would probably not be. Stores only have size 2/3 now, for the most part. It is hit or miss. Sometimes we run out of the "less" popular ones first, because they send us so few of them. Jessie is in the middle, we got a fair amount, but not enough for the demand.
Stores may not have them to sell after Halloween. Some are carried after as "role play", and stay full price, and some get sent to the outlets for the clearance sale.
They have been selling well this year at full price. We expect to sell alot when Beauty and the Beast some out, the presale comes with a great coupon, $10 off any purchase, or $20 off a $40 purchase. MANY parents will use that $20 coupon on costumes, a great deal if you are buying B&B DVD anyway. Movie out Oct 5, so good timing for costume purchase.
Good luck, I love seeing kids try on the costumes. I wish we had the Marvel line for boys, like they have online. Maybe next year.
