Affiliate Marketing Secrets

im about to buy a 16GB iphone 5 online.
(ive had the iphone 4 for a long time and its really on its last legs now)
i have never bought anythihng online like a phone before so im a little worried.
the offer is £36 per month with 5 months free, unlimited calls and texts and its with orange.

im 17 years old and i get £30 per week income. i CAN afford this but my mum wont let me order it an just tells me to talk about it tomorrow every time i bring it up
(yes i still have to ask my mum if i can buy stuff)
she wont be mad if i get it, she just keeps pushing off the subject. and asking her for advise is a bad idea cause she has no idea about stuff like this.
my old phone is actually shutting its self off as i type this its so broken..
i just wanna know if there is anyone out there who knows about this kinda thing and can find any fault or hidden payment or anything like that.
odds are im just gonna go ahead and press ‘buy’ right now unless i can find a reason not to.
i just wanted to double check
please let me know if you have gotten a slimier deal and found any hidden payments or a bad side to this deal. let me know if it sounds legit
thank you 🙂
