My issue with microtransactions is that the cost of making the decision seems like it outweighs the currency cost. Like, I used to buy computer games (e.g. from Steam) when they were on sale. Now I ignore any sale which has a price greater than $0.00, because if a game is free, I don't have to spend any time figuring out whether I will like it.

Where do you see microtransactions being applied in practice?
