I've been trying bunpro (not bunpo) for the past month, and alongside wanikani I really like it so I decided to get the lifetime subscription. Searched on Reddit and saw they do a winter sale for $120, with a normal price of $150. They tried to charge me $200 in the iOS app to upgrade though (which is why I was looking around, it sounded high). I had to go log into their website and pay there to get a proper price. So iOS users at least, beware of this quite large price discrepancy.
