I feel exposed if I leave the house without my little battery box containing a spare 18650, a filled carto, and a little 3ml bottle of juice. I don't want to be in the position of having the urge to buy a pack. I'd probably buy a disposable at a convenience store, but some of the prices I've seen on those are ridiculous. One I saw was $38 and contained one disposable with an extra cart.
It's cheaper to carry the little pocket sized box and not need it. I'm kind of eccentric about filling my Protank before I leave in addition to the backup box. That gives me 6ml of juice total. I'm good for 24 hours.
