@Jon might consider a package deal, such as "XX percent off if you buy every un-owned skin in the shop." Some of our players would probably jump on it.
I almost hate to mention it here now that Jon has been specifically tagged and mmmmaaaaayyyyyybe he's forgotten at this point, $;^ P but Inquisitional Silverfoil costumes are still discounted at half off. I got a couple already. I'd like to get all the non-immodest ones. My RPer inside is torn, though, on the elf warrior because I like him, but he's male, and my two elf warriors I've used all this time are female. $F^ , Sure, I could consider retconning maybe, but I'd also need to rename. At that point, might as well just hire a couple new elf warriors...
