This is question about life style, not money.

And money is not tightly coupled to give back, that is main trouble but also it is relief.

In many cases, with adequate humans, you could pay with some service or give some collectibles instead of money.

So main question, you should know human with which you made transaction and better if you have powerful soft skills, so you could hear what is really valuable for your party.

Good example - you could buy some rare tickets and give to your party. Or in my country once considered good to gift good puppy (for this you sure should know best breeder(s)).

For this is good book "ask your mother", but sure, you should train these skills very seriously, so your party will not got bored while you will negotiate (in some cases better to ask some third party, what is valuable for person).

Good side, with some experience you will become very powerful, so will literally exchange paper clip to house.

PS and don't forget main marketing principle - for success value of what you will give to human should be larger for him than he given to you. Larger don't mean magnitudes larger, in many cases even one dollar (or one good letter, or good public reply to his post), could be enough, but as I said - value depends on internal values of person, so you should really know him very good.
