Dropbox offers only a 1TB plan for 9.99 €/month. Unfortunately a lot of people don't need so much space and they are not willing to pay that sum each month. We want to ask Dropbox to create an intermediate plan, for example 100GB at 1.99 €/month or 50GB at 0.99 €/month. The user will be happy (mainly students and non-pro users) and Dropbox will earn more per GB:

9.99€/1TB = 1 cent/GB

1.99/100GB = 2 cent/GB.
