I believe that in general the price is the same as for a 12 month multi-entry visa, but that price varies by passport.

One more. If you have a passport from an APEC country AND can meet the various criteria (which vary by country) then you can apply for an APEC card which gives you visa free travel into HK and into China for visits of up to (normally) 90 days. It takes ages and costs and there are some hoops to jump, but it is the closest I can think of to a "pass that allows free travel" - IF you qualify.
Yes, nobody knows the 'criteria' for their discretion. Both times I've applied for multi-entries I've been given 3 years so as far as I can tell it is based on good looks and sparkling personality, obviously.
