A nice lady contacted me yesterday expressing extreme interest in a pair of expensive shoes I had just listed. They are EU/39. She inquired whether they run true to size as she wears US 9. Long story short-she requested money order payment. I decided to accept on the basis that she has 200+ fb with a 100% rating. Since I have no experience with this form of payment I decided to pick the brains of those more knowledgable--namely you guys! Any input will be greatly appreciated.
