I have dealt with this seller for years without an issue. But, my most recent purchase was a disaster. Admittedly, this was partly due to me not paying enough attention. But the site defaults to Uruguay as the country of destination. Uruguay!!!!!! ??? That's something I have NEVER seen on a website. So my potentiometer is heading to Uruguay, and they will do nothing to rectify this. This despite the fact that the address I entered was clearly to a US state with a US zip code. I'm not telling people to not deal with this seller. Just pay extra attention. As for me? Lesson learned and relationship burned. There's nothing they sell that I can't get elsewhere, without the risk of it going to Uruguay!
Call them and tell them their web dev doesn’t understand localization. Fire that person. Refund your overcharge. Ship your pot express for your troubles.
I dealt with them last year without issues. User error, or website gremlins? I had a similar situation years ago when ordering from a cd shop.
