This sounds like it might be a useful (will pay money for) service, but I have to say my first experience here was weird and slightly obnoxious. Why do I need to give you an SSH key when I first sign up? Why are coupon codes masked behind the API? When I first started it said I could request one, then I saw nothing.
I did figure out that I can request through your API via command line, but it seems like a have to use a weird unicode heart (/heart doesn't work). After futzing with that I discover all coupons are gone. Awesome.
