Yesterday at the Big Lots outside Franklin Mills Mall, I saw two of the Barbie Disco dolls:
Happy Birthday, Gorgeous Barbie (Blonde)
Celebrate, Disco Doll! Barbie (Brown hair)
Each doll cost $12.99. A friend picked up the Celebrate, Disco Doll! (African American) for me for my birthday; she saw a few of them at the Norristown Big Lots. These dolls seem to have the Model Muse body - extra thin.
The Franklin Mills Mall also had two My Scene Masquerade Madness outfits, for $1.00 EACH. They were the last two out at the time, and I got them. Hudson's boxing outfit and Ellis' pirate outfit. The other two outfits, Sutton's vampire outfit and River's rock star outfit, might be available at another Big Lots.
Note: the Norristown Big Lots has a larger toy section than the Franklin Mills store.
