## Questions & Answers

**Q: How come when we check it on another computer it's only 18 plus ? How come on my amazon account its 20 plus. Do you charge more to members ?**

**Q: when will this get back in stock? also 27 bucks heck no**
A: It's was like $10 when I got it before Christmas. I'm guessing that's the only reason it's pricey now. Walmart may have it!

A: about four inches tall

A: it is a larger than figure exosuit. figure resides in the chest.
