I have just listed one of ds's designer label items on eBay and have received an offer from someone selling a similar coat.
My alarm bells are ringing. Am I overthinking this, or would you be suspicious that they are selling a similar coat of the same size, but wanting to buy mine at a significantly reduced price?
Anyway, I will decline as they are fairly new with ebay score of less than 20. In the old days, you used to be able to set buyer's requirements.
