PayGal! I like it, GlobeSpotter. What's your percentage?
Some fellows utilize Paypal for a variety of reasons, especially if they are from out of town and want to pre-book a longer date. Fancyinheels Entertainment uses it (and Visa gift cards and Green Dot) to take deposits for my annual Texas Renaissance Festival Fantasy Tours, a perfectly legit enterprise. (With optional add-on BCD, of course.) It's only a problem if a gentleman has someone around who might track his finances (like a nosy spouse or a business partner or the freakin' IRS), or if the lady is being really obvious about what she's using it for and too much goes through the account that can't be associated with a purchase site like eBay. For all anybody knows, that $300 sent to Sonya was a belated birthday gift.
I wouldn't recommend it for regular Hobby usage, just exceptional circumstances.
