I ran a lifetime deal for Fjordmail in September. $149 once, forever. 212 people bought it. That is $31,588 in three weeks, which is more than the product made in its first year of subscriptions.
Every thread here treats lifetime deals as a moral failure. I think most of you are repeating something you read and have never run the numbers on your own product.
My numbers: those 212 accounts cost me about $0.90 a month each to serve. At that rate the deal pays for itself for 13 years.
Tell me why I am wrong. Bring numbers.
