I've been wondering about this myself. Does the time get compounded one on top of the other? Or does it start from the date of the review no matter if I already have premium time going? If I write 3 reviews for 3 different providers on the same day does it start over from the last review I wrote or do I get 18 weeks of premium access? I clicked the link and it says my subscription expires 9/2017 I'm confused a bit
