Why is her description ALL IN CAPS - that would put me off as a customer right away.
Yes I sell mainly to the USA and get the odd rude buyer saying well I can get this for $$ so why are you asking $$$ I tell them to hurry and buy it before that seller clears all their stock. Putting your item up for sale on Ebay, Vinted or anywhere is just an invitation to treat (trade) so you can ask what you like.
