A little OT, but regarding the paypal fees, I just noticed that if you do a lot of paypal transactions - you are able to get paypal's merchant discount...
Instead of the regular 2.9% + $.30, if you do 3K monthly its 2.5% +$.30, and if you do 10K monthly its 2.2% + $.30 and for 100K its 1.9% + $.30
To sign up, click the fee's link on the bottom of the paypal page.
