How can you guarantee that they are legit? Isn't amazon the only one allowed to sell this, so how do you get them for below what amazon sells them for? Where are they being dropshipped from? It's a pretty bold statement to guarantee that they are legit, it needs proof when selling items like this otherwise you could get forum users here in a fair bit of trouble if they're not careful and/or unlucky.
Previously you had a JV which was interesting but after research I found it to be one of the most difficult VeRO items to sell on ebay apart from the standard LV, Chanel etc. stuff which would have put my longstanding ebay account at very high risk of being canned. I am aware ebay has limits on certain items per account so of course you're looking to expand, but without solid proof that these are genuine items they could pose a high risk to people's quite valuable longstanding ebay accounts. This is just a heads up to fellow BHW members to be aware of the risks. I feel you should be fully upfront about who/where you got the items from and the possible risks to BHW members' ebay accounts. This might prevent a lot of people waking up to find their ebay account has been suspended or whatever, or possibly worse.
ebay being the Google of the online auction world, they are an absolute bitch to deal with, so you need to have balls and a lot of luck to deal in items like this. Also, if the items are not genuine (which was the case with the previous items you dropshipped) then the sellers are looking at trouble with the law as well (in the worst case). It's much less risky for you to just dropship and stay behind the scenes, rather than attempt to sell on a large scale on ebay yourself due to these risks.
Of course a lot of people will still be happy to make the money despite the risk. I just hope it goes well for them all and that they can avoid trouble with ebay, the law, amazon, or whoever. Assuming all is legit, Good luck to all BHW members involved because ebay are an absolute bitch even if you are selling genuine items.
