When I clicked "Download" from the CCleaner home site, the next screen asked me to pay, but I did think it odd that it didn't mention an amount. So I clicked PayPal to see if that showed the price, and it did. When the PayPal site came up it said $20. I paid it. I have no problem contributing to these free things and I thank the owners for doing them. I do wish, though, that I'd read a bit more before I'd jumped. My fault, not theirs.
