They are pretty good prices but other places usually beat them especially if they have a sale going on. I know Michaels has carts on sale for $30ish though I don't know the frequency (seems a lot more often than it was). A lot of the online retailers/ebay can also beat their prices, but I know thats not really an option for what you're looking for.
Walmart is worth checking out regardless - A lot of times they have carts on clearance
