>>No particular reason for choosing tools as a supply. They can be either. The same for the cases/headphones. It's really okay to divide in any manner that you choose. No solution is more right than the other.
I guess my confusion is just that these 2 categories almost seem redundant - supplies is so non-specific that it essentially seems like they both just mean "misc, doesn't fit in another category." The other categories are perfectly clear: an insurance payment is insurance, a plane ticket is travel, an electric bill is a utility, a repair bill is a repair. But a "supply" can be virtually anything cheap-ish & physical...which is why I was confused as to what this category is actually asking for, how it isn't just the same thing as "misc." Which is why I was trying to come up with a rule/definition, rather than just randomly putting the small physical stuff between supplies & misc.
(i.e. my idea of "'supplies' really means 'all miscellaneous items under $200,' and 'misc' really means 'all miscellaneous items over $200'")
