Hell Puppy: What Amazon (and others do) is present you with extra options you can take. However, those options are rarely if ever "pre checked", and there is always a ton of disclosure and such about what it is you are getting.

Most importantly, none of them are recurring, none of them turn into credit card bombs if you fail to cancel each one individually, and none of them magically appears a couple of weeks later.

My feeling is this: If you have pre-checked cross sales, then you need to have a unified cancel method: One cancel stops everything. Surfers should also be able to see a list of all memberships they have purchased, and be able to cancel any or all of them from a single clear place. Cross sales should never be pre-checked, because we are talking about not only a sale but a recurring. Each of the pre-checks should have a clear terms and conditions link for each item. Sales forms should be required to clearly indicate "total charges today" "total charges in the next 7 days" "total monthly recurring charges" in a format that is both clear, concise, in numeric form, and right next to (and above) the actual join button.

You know if they did that, they would have very, very few sales.
