It's highly doubtful these lines offer drop shipping. Usually a Distributor would offer the drop shipping directly for them, but high end brands usually develop a relationshipo with the reseller and most of the resellers need to go through an approval process.

Large manufacturers typically don't dropship in the sense that I think you are talking about. Smaller wholesalers sometimes dropship. Careful using a dropship though. You need to do your homework, otherwise you'll end up just writing checks to the dropshipper. There is generally a per-order (sometimes per-unit) dropship fee. You should also fully understand their shipping charges before signing up. Some less-than-hones dropshippers offer only a single shipping service and over pack or over report the shipping weight. Ask about refunds, returns, insurance, and delivery confirmation costs as well.
Good luck...
