From the article "Our microtrans game has pricepoints from $0.99 to $349.99 and about 80% of the revenue comes from purchases at the $19.99 pricepoint."
Very interesting. I'm not sure about our games we have big and small transaction and they seem to go one way or the other. However we also use Daopay which we kinda just don't count often but if memory serves me right the most purchases from there are in the $20 range. Of course too we can't offer the $100 option on Daopay so it's not comparison.
My partner is just informing me as I write this article that, yes, $20 is our sweet spot.
Edit: forgot to add something that article touched upon as well
From the article "I'd also like to add that "Sales" events are huge."
It's funny we are still doing a 4th of July event right now (we are carrying it over till Monday at midnight). We've always found that doing sales for holidays or whatever bring in a good amount of money. I'm surprised we haven't covered this before in the forums. The other thing we like to do is get into chat whoop up the community and give away free points, turns or whatever we call them for that specific game. This is how you get word of mouth out about your game and word of mouth is by far the best form of advertising. We'll sometime give away more then what we earned for that entire week. Why? Because this helps push those that never gotten in game benefits and would "never buy online items" a taste of what it's like and once some of them get the taste they like it

Which reminds me of an article from the trenches I never got around to writing. You, the game owner, are an internet rock star

Anyone can join up and play a game, but when you, the owner, show up and actually chat and take time talking to the players it really does infuse your game with excitement

And from excitement comes $$$. Not that should be the end goal but hey paying server costs is really, really nice, buying a couple cases of beer after server costs, is well, priceless
