Paris Pass- Justring.com?

These products are all tourist hose jobs. They are not a 'pass' if by that you expect a single card that does many things. What they are is a package of readily available tourist products you can buy for less once you get there. E.g. the Paris Visite transport pass is almost never a good buy and adding a fee to hand it to you makes it less of one. The Paris Museum Pass is often a good buy for a first Paris trip but you can easily pick it up at the first museum you visit (not the Orsay where the lines make having it ahead of time a value) Other coupons and such often conflict with the other things in the package. e.g. HOHO buses can be purchased if you want to ride them but it makes no sense to have an expensive HOHO pass and an expensive Paris Visite pass for the same period -- if you are riding one the money is wasted on the other.
