I'm not sure why they call it the Superstore. I mean yes...it's quite large but I find it slightly more expensive than Deja Vu and the atmosphere is very cold, dirty, and blah.
My friend might object...she bought over $200 worth of stuff from here once, but if I had time I would have brought her to another store that was more fun and playful rather than going to a costco-like warehouse to buy these types of toys.
