SE - Default 3rd Retainer before Fees

[cearka]

However, if these extra retainers is linked with the Venture system, I won't let that slide on a personal level ( unless they implement it in a way no advantage is gained.)

that's a fairly fair point. if extra retainers means extra auction slots/ventures, that may be a bit of an imbalance (however slight).
if its just extra storage though, that's pretty much a reasonable 2 dollar fee for something pretty harmless.
