Quoted from Scotty_K:I stand corrected! Originally, I searched the Walmart.com site, where the higher price showed up.
I did another search, this time on Google for "Goldlok Robby the Robot", and now the $14.92 price showed as available at my local Walmart. I had a $12.80 gift card from a previous refund, so this was a no-brainer, and I just picked one up.
BTW, this looks to be an exclusive Walmart item, so if you want one, I'd suggest grabbing one ASAP.
It's also available through Amazon, but it looks to be resellers only (and at slightly higher prices). you may be right! Still listed at $15
