I do and let me tell you, I don't know why I wasn't doing these sooner! There are 2 in particular that I joined less than 2 weeks ago and on one I have earned $10.97 so far and on the other I have earned $21.09. I make more with these than say, QuickRewards because I don't do a lot of shopping on line and I am not crazy about doing sign-ups. All I do daily is click on the PTC banners (which are mainly for other PTC sites) and the TONS of PTR emails that are sent.( each worth anywhere between 2-10 cents each) I must warn you, if you are not crazy about receiving a lot of emails or you don't check your email often these are not the programs for you (example: I came back from my 4 night cruise and I had 230 PTR emails waiting for me ) If anyone would like to check them out, feel free to pm me and I will send you the link.
