Late to the game, just started getting juice from mount baker , this stuff is awesome!!!! And a 15 ml bottle at 12mg sample for free?? Insane, not to mention the quality, shipping speed and selection , and the prices, this is the best place ever!!!!
You can ask them to mix your freebie at whatever mg and pg/vg ratio you use.
No sense in getting a freebie you won't use so they won't mind.
