Supplier offers to sell trademarked products.
Brand owners control their distribution channels well; if you can’t get their products from a distributor in the United States, it is unlikely you can get them from a distributor in China. In all likelihood the products are either counterfeit or don’t exist. You can always ask the seller if they are an authorized distributor and check with the brand owner in the United States whether the seller is an authorized distributor. There are too many stories of people ordering five iPods, at best, getting three dirty sneakers delivered.

If you are looking for replica items then i guess we all know that China is the right place for that.
