Max, if, make that a capital IF I'm in a hobby shop that is having a sale and I'm in need of some glue I will buy it depending on the price. If you store your glue in the freezer and it has the cap on then it won't harden or go bad. I was in Hobby People one day while they were having a sale, I bought some glue and discovered there was a box with screw on caps/ends/tips bellow the glue, these were a free item!! Now I have a cap for all my old glue bottles. Those bulbs John uses are great too. You can keep your main bottle in the freezer and have a bulb of glue on the bench.
Even in an 8 ounce bottle I have tended to use up my CA long before it goes bad. Not to mention living in an area with 6 or 7 percent humidity my glue lasts a bunch longer them in most places. Now that I'm hampered in my building and not doing a lot we will see how long it lasts. I think my garage freezer will be storing some glue now!
