I would hate this, especially if the dog walker made you use it to get a discount or something. I'm not a fan of PayPal at all. But I agree, it sounds convenient.Michelle, the dog walker I had before we moved (haven't found an new one yet) used a monthly billing using PayPal. You could sign up for what she called a "subscription" and your credit card was billed for the subscription period. I really liked it, gave me on less thing to keep track of.
