I dont offer 30 day subscriptions. I sell CSB bundles which are for 7 days worth upvotes. You could buy 4 bundles which would be x1 per week for 4 weeks.
I offered the extra 2 days as a courtesy. I need to manual vote the extra 2 days. I might offer a monthly subscription at a later time as it's a good idea but for now i would like to build some ground with weekly subscriptions.
