Well I came to know about amazon when I bought my first phone from amazon.got it with in just 3 days that too with good packaging from that moment I am a big fan of amazon;
If I am not wrong I buy must of my products only from amazon.i generally use other sites in case that product is not listed on amazon or has been sold out.one thing that makes amazon ahead of others is its customes care service.if you have any problem related to your shopping just msg them on social media or email them they will contact you within few minutes.
