Unless the rules have changed, and heaven knows they do, if you (the importer) have not filled out the proper documents from your govt to prove legal ownership, what could a US store possibly apply for you with the US State Dept?
Some items are ok under the $100 provision but most stocks are over that.
The question the US govt wants is "who is the end user?" and can they prove they are who they say they are and do not have any legal restrictions.
There have been several US "exporters" that have 'done the paperwork' over the years but unless something has changed in the last few months, they are taking a fee and doing zippo.
As tiriaq so nicely outlined, just because an exporter supposedly does some paper work for you, IF the manf company is not licensed for legal export, the product being exported is illegal.
Again, maybe B&C has jumped through the hoops recently, but if they haven't, their products cannot be legally exported out of the US no matter who fills out what.
