I ordered 500ml 100mg/ml from NN a month ago, and they accidentally sent me an extra 500ml for a total of 1 litre.. emailed to tell them, and they said I could keep it.
Already had 240ml on hand and only vape about 2mg so I should be set for 14yrs and I thought
that was a lot!
Thank god I bought a mini fridge with freezer last year for the garage... you might consider one. It was only $130 from WM. Cheaper than a deep freeze, IIRC, and the fridge part is handy too. (Though they say nic is best kept in a deep freezer, my nic has always tasted great and unchanged in color even after 6+ yrs in the regular old fridge freezer.)
