I listed an item and I didn't realise I had not put a reservation on the cost-my error completely. It's my daughters so I feel I couldn't sell an expensive perfume for 99p-emailed and explained to buyer and they threatened negative feedback if I don't post-what's your views? Can I avoid negative feedback- or is the only way to continue sale. I don't do rude people and they got angry that I didn't reply straight away-I was busy with an Easter egg hunt with the children-feeling upset ☹️
