Hi chicscape, and welcome
The liquidated market can be a good avenue to source these types of products, you just have to always make sure you know what you are buying as there are a few areas where you can come unstuck when dealing in this market.
I would suggest taking a look at Link hidden: Login to view, they really are a very customer friendly supplier, and will be happy to answer absolutely any questions you have about their products at any time.
Of course we are talking about buying in certain volume here, not drop shipping, so it may well not be the market you want.
As Planes has highlighted above, some of those brand names mentioned are not going to be available to you as new products because of their licensed distribution network.
I would suggest contacting firstname.lastname@example.org, and give the team some specifics so they can see what suppler leads they can generate for you.
