He used regular Magic, which is not Magic+. Magic is significantly cheaper. (Drop the plus from the URL). You submit a request, they give you the total, you confirm it, that's what you're charged.
I wouldn't consider myself rich either, but I do fairly well for myself as an unmarried guy in his 20s, and there are some friends that in some situations I wouldn't hesitate at all to spend a few hundred dollars on them. Some of them have done the same for me.
If you don't think twice about buying things under three digits, depending on frequency, just not doing that for frivolous things for a few weeks could afford you the ability to do something that might ultimately be a much more valuable memory. There's plenty of crap I've bought and barely used that would have been much better used taking a good friend out to an extravagant meal or event.
