I placed an order the other day with Mt Baker Vapor. I forgot to change the nic level from the standard 18mg to the 6mg I've been vaping lately. In fact i didn't notice it until I was checking the status a few hours later. The order forturnately hadn't been shipped yet. I sent them an email informing them of my mistake and asking that they change all of the juice to 6mg. Less than an hour later I received a confirmation that my order had been corrected.
