Sigh...not this conversation again.
I will tell you my opinion on this matter, I have been buying high end items for years now, but I have never bought anything high end from Ebay. Perhaps because I live in NYC and have access to basically anything that anyone could possibly want or need - we all know the saying, if you can't find it in NY, you probably don't want it!
Anyway, it wasn't until I came across a lovely pair of CL shoes a few months ago that slipped out of my hands did I start searching on Ebay for *that* shoe. I came across a famous ebay seller, we all know who, that had this shoe, and I couldn't understand how she was able to get so many pairs of this shoe that I knew to be sold out. I thought to myself that perhaps this seller has a retail store and is an authorized retailer of Louboutins, oh how ignorant I was at the time, I later learned the real method of acquiring the shoes.
In any case, when I actively became a member of TPF, I realized that a lot of people that I was chatting with on TPF were also selling items on Ebay for a profit. So I figured, I would give it a shot...and well it worked.
At this point, I still feel that it is unfair for an individual to wipe out the entire stock of one specific style at various stores, but if you don't like it, then don't buy from them. As far as I know, it's not illegal and I've had conversations with an SA that actually works with one of these resellers, and he actually values her business because he knows that it is guaranteed business/commission.
But now that I know that there are people on ebay that do not have access to the various stores that I have access to, when I shop for myself, I pick up an extra pair of shoes and list them on ebay.
I did actually stock up on a well loved shoe when I finally found it because my GF was able to hook me up with a good discount. And what I learned is that people are willing to pay hundreds of $$ over retail just to get a shoe they love which is why famous resellers are able to 'stay in business'. Isn't that the nature of ebay? And I am sure that we all notice how certain items become more frequent once sale season starts, just do a search for shoes that have been marked down and you will see tons of them on ebay listed at the original full retail price.
