I know NOTHING about these toys as I think they are unnecessary and there are better toys out there for this age range. HOWEVER, with that being said, just buy 2 of the more expensive one, get the cheaper one as well, keep your receipts and "sit" on them a while--walmart has a 90 day return policy I believe, and return whichever you don't decide on. That way you have it, get the sale price, and can always return what you don't need.
