Stupid question, but do the Muji stores in Japan actually sell items at the prices printed on the stickers of the items?

We recently learned about Muji stores, got excited because it's kind of like a higher quality Ikea concept (minimalistic but good quality and relatively cheap), and went to the one in San Francisco. Well, the prices at the San Francisco store were not anywhere close to what the prices on the labels were. Stuff was nearly double in some cases.

For example, an eraser had a label of 70 yen, but was being sold for $1.25. There were chopsticks or a bowl or something in the kitchen area that was sold for $13 with a label saying 700 yen. Many pens were $3-6, going up to $10. That's the same as just going to a store in Little Tokyo. The whole store basically ended up being fairly expensive, on par with a Nordstrom or something.

Are other Japanese stores with locations in the US like this as well? For example, is stuff cheaper at Uniqlo at their Japan locations vs the US? I'm wondering if I'm going to have to buy a few suitcases and load up on my shopping when I go there.
