Yes, I came across this. :-) I do not think there is a way to change this wording, unfortunately. (Although it must be!)
The only thing you control is the name of the item being acquired. I ran into this myself. Your only alternative (at least I know) is to name your IAP products so that they "read well" in this dialog box. Thus, your โ5 creditsโ could be better called the โCredit 5 Packโ. When you read "Do you want to buy one 5-Pack loan for $ 3.99?" at least it sounds like english .:-)
