[Skunkworks] OT: Buying stuff from the US

Hey people, I recently came to find out that most things are chepaer when purchased from the US, rather than from the UK (even after the GBP started falling after Brexit). I am currently looking for how I can ship in stuff from the US fast and in a cost effective way. I already know of Salabed, but they just do not respond to emails in good time. That is not the issue though, I'd like to hear of alternatives to Salabed and their rates too. Thanks in advance. S.
