best prices, reliable. I have bought it myself a few times.

If you dont trust that: try InstaGC or Prizerebel or Gifthulk

Do you have paypal or something similar?

yep, sorry i forgot to say, i do have paypal and a debit card attached to it

I saw itunes cards on markets, like Carrefour and similar, but the currency is €.

you could always find a trustworthy friend and pay them to buy one for you?

If you're not in a hurry and have an iOS/Android smartphone, you can use FreeMyApps. You just download free sponsor apps and leave it open for 30 seconds to earn credits. You can also get Amazon gift cards. It's not scam like many other alternatives out there. I've made nearly 200$ on my iphone and ipad in 2 years with just downloading couple of apps every week.

If you have a paypal you could try this. PayPal Gifts

I have a trusty ebay seller which I pay 1USD over the nominal price (i.e. 101 USD for a 100 dollars). I already bought from her more than 2k in credits and she's a fast answer. If you want her contact, drop me a message at steam.

Ive sent you a message on steam, I had a spare code I'd never need so ive sent it. Hope it works ^_^

Steamtrades.com is a pretty good place to get itunes cards at a decent discount.
