A slightly different Vinted annoyance - when I've saved something to come back to later and I immediately get a message from the seller along the lines of 'hi hun, I can get this posted out to you today, just make sure you order now or it will go'
It really puts me off, and in spite of myself as I could probably get a decent bargain, I un-save it and don't reply.
I think it's the 'hi hun' especially that makes my teeth itch.
