Here's a BedokFunland JC tip : log into your PayPal, go to "My
pre-approved payments", and cancel everything that you're not
actively paying for on a regular basis. Sneaky merchants like to
force you to put them on your "pre-approved payments" on the
initial billing, without most customers even realizing it.
