No. Still, I don't make the rules.
I hate feeling like a tyre-kicker when I'm shopping around. I recently decided it'd be nice to get a Tourbillon watch and looked at Jos_Nana's ample collection of Vachequirits and Buggerits and decided to ask the price, all enthused about getting a technological marvel.
I got the reply of around $650-900 or so, which depressed me. If I'd have seen the prices, I'd not have messaged him. I'd have looked at stuff in my price-range to get enthused about and he'd have possibly got a sale. I'm now feeling a reluctance to IM dealers in case I get that same disappointment. I'll stick to dealers that post prices from now on.
Precious Tim, TimeToKill, Narikaa ... you are the sorts of dealers that will be getting my business from now on. You and Silix-Prime, when their site responds faster than a turtle wading through treacle with a brick duct-taped to its back.
For the record, I believe trustywatchguy also posts his prices, but I've not had any dealings with him yet. Hmm ... I wonder if he takes pp.
