of course!
the sponsor can choose the life time of the cookie
Minimum is 3 days (maybe less im not sure anymore), maximum is 365...
Very few sponsors advertise about the CCBill cookie length. The only one i saw was this
one with a cookie life time of 4 months... not bad
It really makes a fucking difference in the end if the cookie is set to 3 days or if it's set to 365....
