Have 2 questions
a) is this still in sale and how long
and
b) if this is free this year you can also use the free version of VBUCKS farms or only with the paid?
No, it's not on sale anymore and I suspect that in the free version of RdW - if it comes out - there will not be V-Buck Alerts etc. Or "other" V-Bucks, as everything else would be unfair to the buyers
