They have a 'store' link [1] right in their header with all the pricing. They could maybe be a little more upfront about it, but it's not really a bait and switch. Also, the prices do seem fairly reasonable for what it does.
The only thing holding me back has been not having great mobile access (as far as I can tell) on Safari on iOS. Looks like iOS 8 will change that.
I think they purposely avoid putting a "Buy" link on their product page because they want to get people started before revealing that the software costs money (and a lot of money for a password safe).
IMO it's not far off the equivalent of how tourist trap restaurants in Europe put out bread on the table (something provided for free in many restaurants) and then charge you if you touch any. FWIW, that's considered pretty slimy behaviour.
I've used 1Password for years, and password access in Safari on iOS has indeed been a pain point, but still been manageable. iOS 8 will make it much nicer, with the 1Password extension.
I checked the 1Password site and it seems like a bit of a bait and switch. Download links without any mention of a price or trial anywhere on the product pages until you create a vault and see a License link in the menus. Then $50+ and another $10 for the mobile app.
I'm sure it's worth it, but I'd much rather they spell out their pricing up front.
