Money Money Moneyyy... MONEY

[Sundance]

I think someone else suggested this before but, Random junk catalog.

The random junk catalog would have random trinkets and doodads to order from at a low cost (but low quality). Things like toys, neat trinkets and clothes.

At the high end you could buy cool stuff like a nontraitor clown car, or maybe a segway. Cool gadget things to show off your mad money making skills.

On the low end things like colored pens, candy, some cheap plastic toys, etc.

There's absolutely nothing stopping shuttle dealers that I suggested above selling all the random trinkets and doodads you suggested. It'll be like a regular old flea market. If cocaine ever gets added, it should give you temporary haggling skills (complete egoism) like the hop's suggested genetics one. It'd be like wolf of wall street space simulator.
