You are the exception. Very few people who wouldn't pay $10 would pay $5 or $1, no matter which region. If your salary level makes $10 an important amount of money, then priorities should be food, shelter and such. And if you need five months to save up for bike parts, then you have to urgently try to fix your economic situation, before you put your own health and future at risk.
I feel sorry for you. On high horses there must be awfully thin air and that can cause nose bleed I heard.
omg... what?
What's high about my horses? When $10 is a considerable amount of money for you, that means you are broke. If on the other hand, you don't think the product is worth $10, then that's it. I see it every day hackers talking about how they cannot afford $5 or $10 for something. If they are honest, then that means they are living in poverty. If they are not living in poverty, why not just say "I don't think it's worth my money". Why the charade?
There is a huge difference between $10 and $10 a month. "Afford" is not necessarily the right qualifier. Frequency of utility is pretty important here. My apple music sub costs $16 for my partner and I. We both use it extensively throughout the day. I might plan a new bike route once or twice a month.
If $10 per month or $10 once is an important amount, that means the person is broke. Like you explain yourself, it's not that you cannot afford the bike app, it is that the product is not for you, ie it's not worth your money. Most things are not worth our money. That doesn't mean we can't afford them.
