Interesting. I have a question for the seller.
If you purchased the shoes new from AE, then decided you didn't want them, why not return them to AE for a full refund? For you to sell them "at cost" you actually lose money with final value fees, paypal fees, etc. are considered. Your best financial option was to simply return them to AE.
You can return them to AE anytime. Why did you not go this route?
