No source talk so No! Nobody has a supplier and we don't discuss shipping methods in the open!

Any top source knows exactly what their doing. That is why they are ranked the best brother.

Any source worth his salt would be willing to remove the labels (or not put a label on) for you. Customer service should be number one. (especially considering the margin they sell their product over)

That being said I've never personally asked so I don't actually know. Good way to find out would be to ask the SRCs. Better yet ask the SRC you plan on buying from.
