I'm working consigning a portion of the nectar my current Sim is making, just to see if my Sim sees any benefits from consigning a large number of items over a period of time. He's been selling at least 3 bottles of nectar and / or fruit/veggies a day ... the game doesn't report
everything that was sold at 5:00 when the consignment store closes its books, just the "top three sellers." Short of checking daily (and keeping a list), it seems the most valuable / expensive stuff moves before the less-expensive things, but I've yet to have anything NOT sell.
I suspect consigning is a "hidden" or "secret" Skill (a lot like Dancing was in the Sims2 ... you got better at it over time, but you couldn't tell exactly how good the Sim the was except by watching him or her dance, or in this case, if profits go up significantly the more you sell stuff).
I don't think I've yet "testingcheatsenabled" in-game yet during play (I've tried a few times to fix a broken Sim or messed up save / town), but it's possible the value is there somewhere. Dunno. <shrug>
Traffic at the store is a bit strange ... it seems it opens around noon, and my Sim performs a song or two there every time he goes over (just to crank my "Number of Songs Performed" Value!). Sometimes it's very busy (at least for me), but most of the time it's deserted.
Like a lot of "real" consignment stores.
And I've never seen another Sim attempting to interact with the shop owner, but then in the Sims3 I've
never seen game-controlled Sims ever hit a register (unlike, for instance, in
Open For Business in the Sims2).
I guess the game just generates random pictures with random sims having made it. I don't fing Sir Landgraab did really consign the painting. If he did, I would be surprised.
Illuminator, I'm sure that's what the game's doing, just populating the shop with random what-not with miscellaneous "created by" tags .... but one of the things I've always found fun in the Sims was to make up mental stories of WHY something I see happen in the game happened ... obviously Sir Landgraab's doing market research about the consignment store, wondering if him or his clan should buy the shop up! hehe
