This isn't criticism of your service per see, but wouldn't scheduling flower delivery take out some of the magic and fun of receiving flowers? Maybe you could add some randomness so that the flowers are delivered within a interval instead of always 30 days apart?

Did you do some research to figure out the MVP?

I understand that you're in the MVP phase right now but what are your plans wrt to the web design? The current one is very generic. Maybe some kind of flower shop design?

I like the idea of the rookie plan :) How does your email reminder look like? I'm betting you made it easy to sign up for one of the other two plans, maybe even offering a rebate on the first delivery of roses?

You might want to align the plan boxes on /pricing as "rookie" is shorter than the others.
