I want to ask any sellers here ever have problems with this gurantee? I mean did any buyers tried to mess up w/ you claiming your item is fake after receiving it and request for money back? I am new to eBay and I sold a LV few weeks ago w/ money back guarantee, so far no problems. I am selling another LV and this potential buyer was asking me a lot of questions regarding authenticity and I did try my very best to fulfill her needs (she sounded like she wanted to buy my bag but she is not 100% sure of the authenticity). So I decided to take out the money back guarantee because I was scared that she might be one of those trouble buyer. Ended up she said she didn't feel right cuz I am not offering her the money back guarantee and the duplicate receipt I showed her wasn't print on the LV logo paper (I went to the store especially for her to request for a duplicate receipt, and what I got from the store is a duplicate printed on plain paper). Anyway, do you think I have done anything wrong? I also really want to find out if any sellers ever have problems w/ offering money back guarantee on authenticity. Thanks!
