As of November 2015, Samantha has been gifted 150,000+ Otto (because I get unnecessarily stupid amounts of points at times). Between her limited potion sales on order, her repeated taking of "Special customers" with violent/heavy bdsm kinks impossible with most other prostitutes in the house/eros and these vast influxes of cash, I will not be explicitly tallying purchases.

Most of her money goes towards either individual, specific plots (such as humanitarian work in Sanae's name, or her plot with Umi Ryuuzaki.), but she has ample cash to make pretty much any normal purchase or gift she wishes at this time.
