Made To Move Barbies at a Reasonable Price?

[WaterDraw]

Hello! I am currently trying to make custom dolls for Heathers: The Musical (these will also be my first custom dolls ever), but I am having a bit of trouble. Since these dolls are most likely going to be going through a lot of photo shoots, I decided to go with the Made To Move line of Barbies with the extra pose-ability. I just have one problem; I cannot find any of these dolls at a reasonable price for the life of me. Even my local Toys "R" Us which was closing down only had the dolls off at 15%, meaning I could only manage to get one since the dolls were priced weirdly high (I think at like, $25 or something which is weird because the last Walmart I went to had them for $15). Of course all the listings on eBay were $40+...I love Heathers, but I am not willing to shell out $40+ on a doll that I could usually find for only $15.
So I hand the question to all of you, do you know of a place were I can find Made to Move Barbies at a reasonable price? Of course I would normally just go to Walmart but the Walmarts I have been to seem to be all sold out of them...I live in America if that helps. Any advice is appreciated, thank you all!!

Maybe you could check thrift stores? I've seen quite a few at local ones when looking for ponies.

That's a good idea! I usually try to look for dolls in general, but my stores have been sort of dry as of late. 
Wish me luck though!
