OK, So I just bought an iTunes giftcard, ($15), and I redeemed it in the appstore, so I was browsing around, then I decided to check out the iTunes movies and stuff, so I bought some stuff (Trailer Park Boys Season 1, and the XMas special Please Register or Log in to view images, and South Park epi. WTF?) and it left me with an account balance of $3.01 so I went in the the appstore, and I saw this cool looking app called iTim for 2.99, and I thought, awesome, I have enough! So I clicked "Buy Now" and typed my pass an everything, it put me to the SB, and the app started downloading, but then a pop up said something about iTunes store credit..? It says I dont have enough or something? Help plz lol, I dont really get apps in the appstore except the free ones, so im inexperienced lol. Just a little footnote: When I created my iTunes account I clicked no credit card, cuz I dont have one, and im thinking that has something to do with it? Thanks!
