Thanks for clarifying and I understand your problem now.
I'm quite surprised to hear that the Drop Shipper insists on sending the products in branded packaging, Drop-shipping is usually done blind, so I'm quite confused by that aspect.
Is this a supplier in our directory, if so can you pass on their name so we can follow up with them to clarity please. I think our best option here is to try and see if we can get you two working together or find an alternative supplier that will blind ship for you internationally. I'm not sure what the chances are of finding a fulfillment company that will repackage like this, but may be possible as a last resort.
Even if we can find someone who will re-package and ship for you, chances are that level of service will destroy any possible margin you would be making on the sales to start with, so let's just work on plan A to begin with and see if we can get that working before looking at option B.
You can PM me the supplier details if you would prefer to keep that private.
