Hiya!
Well, I'm a stingy "son of Graz'zt",

, so my players PC's buy mundane stuff like horses, better armor, more food, more rope, more torches, more oil, more iron spikes, more sacks, more wineskins, more wine for the wineskins, a cart or wagon, tents, maybe a few nights in the "luxury suites" at a really nice inn.
So far they've only once managed to get enough coin to actually pool together to buy an old run-down manor house in a rather poor town. They were planning on making it their "adventuring guild headquarters". Worked ok for about a month, then something very, very bad happened in town that involved failing to stop an evil cleric group from mass-raising (as skeletons and zombies) just about every corpse in a 1km radius; including the hill giant corpse that proceeded to do serious damage to their "adventuring guild headquarters". Needless to say, they were pretty much broke after that.
Always keep 'em hungry for more o' that shiny stuff!
PS: As for magic items...as one of my players said last year... "Magic items? Wait...this game has magic items?!".

As I said, I'm a stingy SOB.
