I have had a similar experience with MEK. My local hardware store (now gone) was nice enough to special order MEK for me, but I had to take a full case consisting
of four 1 gallon cans. I’m still on the first can which lives in my garage.
I have a standing offer with all local friends. FREE MEK. Bring your own tight seal jar.
Last time I was through the big box store I saw that they now have MEK in 1 quart containers. That was not the case 15-20 years ago.

When my employer closed down my prototype printed circuit lab in 1992 I liberated a 3/4 full gallon jug of MEK that was slated for disposal. I've only used it occasionally since I began resin casting, but it's still good 28 years later
with minimal evaporation loss. It's in a glass jug with a lined plastic screw cap in our unheated garage.
