I got three of their house fans from Costco a few years ago. Great fans - low power draw, good looks, includes a nice light, good noise profile, etc.

The fans didn't include wall panels, which I wanted rather than only remotes. No problem, I figured I'll order 3 of them from their site. However, there's an obvious bug in the shipping calculator, where the cost to ship three little wall boxes came out to $40+$40+$40 = $120. (And where the shipping page called this a "flat rate".) If I wanted to order 50 wall boxes, the shipping would be $2,000! The shipping cost was completely incongruent with other items in their shop - e.g. I could order 100 branded mugs for a flat shipping charge of $40. (And this is on top of the wall controllers that where already $123 each for some pretty simple electronics.)

I had probably a dozen support interactions over a couple weeks over both phone and email trying to get Big Ass Fans to fix their broken website and/or just put the wall controllers in a $30 flat-rate shipping box for me before we finally settled on a $55 shipping charge where I still felt like I was getting ripped off.
