I followed a tip submitted by two posters at the Pink Parlor about a sale at Target. The Grease Barbies, the Alvin Ailey Barbie, and the Catwoman Kelly/Batman Tommy dolls were on sale at $17.48 for each Barbie and 7.00 for the Kelly set. I found the Alvin Ailey Barbie for $17.47 and the Kelly set for $7.47 at the Springfield Target.
Here's the link for Pink Parlor:
I'd wanted both the Alvin Ailey Barbie AND the Kelly set, but I thought I would wait until the prices were reduced -- oh just a little. Lucked out at those prices. Got one set each.
