If the company is a CT company, doesn't have any business presence (e.g., sales outlet) in CA and isn't some type of affliate of a CA company, then they should not be charging you tax -- even if it's drop shipped from a CA company.

Edit --

I just looked at their site and their terms -- which do state upfront that they will charge sales tax in CA. I'm thinking that there's some agent/reseller relationship between ASE and Bend-Pak. Seems that perhaps Bend-Pak may be technically making the sale with some type of kickback to ASE. Who knows whether that's a legit setup or not.
