If you're interested in anything, I can get you some prices...
I've been actively collecting on and off for about a decade, and while I have a few costumes sourced from your company's predecessors' eBay auctions, I never bought anything directly from their website. I've bought directly from just about every other web outlet you can think of that was around during those 10 years, except for theirs/yours.
Why was this? I found it way too annoying that they didn't just list prices for items. Having to inquire about every listed piece I might have an interest in was just too bothersome when there are at least half a dozen as-good-or-better items I'm interested in listed at other sources at any given time. I inquired once about prices for a few items, and two or three items on the list made the cut into what I'd be willing to pay offhand, but they quickly fell out-of-sight-out-of-mind on my list of things to acquire as money comes in just because there's no website with prices to go back to and say, "Yeah, can't wait any longer--I'm buying that."
I don't know if your company is interested in getting into the upper end of the retail/direct sale business or whether it's content with its current way of selling largely through auctions, but if you're ever interested in expanding your retail sales you really need to post at least some items with prices. Even if the prices you'd feel comfortable listing publicly are on the high side, you might be surprised at the sales that could result when there are actually prices of any sort listed. Items without prices attached remain vague and doubtful purchases unless they're someone's dream item. Items with prices attached are an invitation to stick in the customer's mind and get him thinking, "Isn't Y worth $XXXX to me now, and if not is someone going to buy it out from under me while I think too long or buy Z from Propstore hoping to get this later?"
Just my two cents' worth.
