Amazon shows prices, Apple shows prices, small shops on Etsy show prices, Craigslist, Kijiji and everyone knows eBay shows prices. I'm sure you can find more, and they've touched almost every single online user, this is what people expect.
People want prices, people want fast, if you make anyone in any market work to get the information they need, they can easily find someone else online who will make it easier for them.
Don't Kid yourself to think they'll be 'intrigued' by the mystery and give you (the dealer) their time first.
