Is Amazon a reliable source?

I'm thinking about buying an iphone 5 from Amazon but i'm not completely sure, is Amazon reliable for iphones? Can i still get applecare for it if so?

Yes, Amazon is very reliable. You get things quick. You can use a gift card, they sell Amazon giftcards at the store, or use a prepaid card, which works just like a credit card.

Amazon are ok by themselves but often use Third party traders so it might be ok if its directly from Amazon make sure they have it in stock and they can guarantee delivery, but you always take a small risk buying things off the internet. Especially Electronic Goods.

Always use paypal because then you have a little more protection

If you buy directly from Amazon then yes but from a third party you can never be sure
