I don't know if you would be able to do that or not. There is no need to do that since they have a plan that offers a monthly updated 3B report for $39.95 a month. I have that plan. This plan includes all 3 bureaus. I don't see it on the ptoduct page so you may have to call to get it. It's called Fico Ultimate 3B+.
Fico Ultimate 3B+ upgrade is available on your dashboard. You pay the upcharge for the current month, then 39.95 every month thereafter.
I too was thinking about canceling my subscription, then just resigning up for updates. I'm sure there is some small print somewhere that may prevent you from doing this.
