Query: Tend to run large and the Marketplace vendor is a crook

Buying shoes online is always chancy. You can't tell if they fit or not until you try them on. For that reason, Amazon and many other merchants allow free returns. As it turned out the boots were too large for me. I was surprised since I have two other new pairs of Timberland shoes that fit perfectly.So, I requested a return. The vendor, Frankels of Brooklyn NY sent me an email with return instructions. I was very surprised to find that they charge $10 for a return. Add the $20 UPS charge to ship it back to them and you are looking at a big penalty for online shopping.But that's not all. Frankels notified Amazon that they shipped my boots (which triggers my credit card being charged) but failed to ship for nearly a week after that. Pretty dishonest.If you want these boots, check to see if the vendor is Frankels. If it is, go elsewhere.
