bought too much nicotine concentrate, gamble it wont go bad or sell?

Hi all, been hoarding for vape mail ban. hope my slowtech orders for hardware come.
said the big thing to buy was nicotine, I might have over done it. calculated it out, came out to 7 year supply of 100mg liquid concentrate.
I am not sure it will keep for that long in dark cupboard, lots of mixed opinion's on on web,
cant afford a deep freezer etc. Some I read said dark place fine, others say must be in a freezer,
anyone know shelf life for sure if but in amber bottles and in dark cupboard….
