I've been wondering if independent software vendors might benefit from some humanizing of the sales effort. Instead of charging $2 for an app, how about framing it as "buy the developer a taco", or for $4 "buy the developer a grande latte". The amazing $10 app could be "buy the developer a roll of sushi". You get the idea.

Psychologically, I find it much more satisfying to be rewarding friends & associates with more tangible things than some dollar amount.

Does anyone know if this model has been attempted before?
