Recurring payments: Amazon Prime, Spotify, NearlyFreeSpeech and A Small Orange for hosting, planning to cancel Audible and Wolfram-Alpha because I never use them

Paid for once: Threes, Clear, Convert (for all of my unit conversion needs)

I use but don't pay for: Dropbox, IntellijIDEA, Sublime Text 2

I've also spent a shameful amount of money on Candy Crush...
