VA's are a bit irritating. Yes they work, but they work because of marketing principles, not because if gives your buyers a 'good feeling'.
Once a savvy buyer has seen this 3 to 5 times they now know this is bogus.
When I see this, I think, "Just give me the price upfront --- stop the games". My personal opinion.

I heard that Adwords doesn't like these ... so you'll get slapped if you try to direct link to these pages?
I say, forget the VA's ... yes it was clever and it'll work --- but it just makes you feel like the merchant is sneaky, gimmicky and not really laying all the cards out on the table.
