That's the gist of what I was hoping for yes. The problem with the other scripts I've seen is that you end up with (at best) 1 auction per item type, which, while better than one per item, is not always ideal. Based on what I've seen on Kbay and what I've sold in /trade most buyers are only interested in two distinctions among stuffies: Regular and VIP. So as long as you kept those two classes separate you could bundle together as many stuffies as will fit in one auction. In fact you could probably even get away with putting the whole lot together as there are very few buyers picky enough to ignore a whole auction just because it has a couple of things they don't want in it. And I guess you could add options for extra customisation as well (eg: 1 auction per item type).
Min bid is easy. Just make it a percentage (say 90%) of the hard coded or user defined values for stuffies I mentioned before (there are really only a handful different values to take into account here, regular, VIP, chests, handbags, heart necklaces etc.). The prices on stuffies tend to be fairly static, and most people aren't going to mind if they miss out on one or two hundred meat here or there if it's in the interests of automation.
Wish it was even older... I could have used this from day one! (Well, kinda). Aside from Mafia itself this is easily my favourite and most used addition to KoL.
