Replying to So fucking done with shipping shit

How the fuck do you guys sell stuff on the bst without any problems? I've run into so much bullshit...recently shipped a pair of skates to tHE UK and the USPS website said $65 flat rate shipping and they charged me $95 at the post office. Now the guy receiving it says he paid €50 in customs and I told him I'd cover it because I know I shouldn't make him just eat it. So in the end I pretty much made nothing off these skates, fml. I shipped them a couple weeks back and he still hasn't fucking gotten them.
Exorbitant cost bullshit like this has happened to me before this and in other situations and I'm fucking done with it, I'll let my dumb sports purchases pile up in my room so everyone can see how much money I waste. Fuck it. Fuck USPS, fuck UPS, fuck everything.
