Really? Are there really so many sites that you don't trust, yet have they have your credit card info? I can't think of a single site that fits that bill for me

Really? Are there really so many sites that you don't trust, yet have they have your credit card info? I can't think of a single site that fits that bill for me. If one did nefariously charge me for something an make it a hassle to cancel, a chargeback would be an easy solution; it's not likely I want to maintain a business relationship with them anyway.
