how would you pay for the stuff you bought after you spent?

if was some kind of game that I need to spend 10M dollars and cant have anything left at the end I would:

bribe someone to make $1M or $2M be "spent", but instead they would go to my pockets in secrecy
buy stuff that I could use as investment or that have intrinsic value, like gold, or hot dog cars, or anything that the rules would allow
help others, if I could

I don't need lots of expensive stuff that would only cost a fuckton to maintain
