I have no idea how this is working with the app store but I know that on the Android play store to request refund was not simple. Now you'll have to get out of your comfort zone for let's say $0.99-3.99 - something you wouldn't even consider (your time is more valuable). Disputing that charge is even much more a time sink than asking for a refund as you would have to probably sign on several forms and fax them back to your credit card company, then you always have the possible cost of the chargeback being denied (I know my CC impose a penalty of $10).

I would say anything beyond $10-20 would be worth figthing. Of course it depends on where you are located (I would imagine someone in a poor country more likely to fight for a $5 refund than in a rich country), and your socioeconomic class (as I would imagine that a 18 unemployed year old would more likely ask for a refund than a 45 year old professor at Standford).

Just my 2 cents.
