Hey sajha,
How does the Prime membership in the Amazon works. Can someone help me to understand regarding the fee. I sign up for 30 days free trial but it says it will charge 79 a month after 30 days. how much it will charge if i cancel the membership. Does it worth it or not? i don't know

Thanks
 

If you canceal before 30days it wont charge you anything. If it worth? It depends how much you shop on amazon. For me it worths as i do some shopping and dont forget prime means free 2 day shipping and you get free prime videos and movies to watch on computer xbox ps or roku like amazon enabled media players.
Besides that if you use your student e-mail adress you can get student prime membership which i think 6 month free and $40 a year.

I tried it once. They deliver within 2 days for prime members however, i cancel it. I oreder early so I dont need that. You can cancel it

 if you shop at least 5-6 times a year, and dont have subscription to netflix, its worth it. 
and if you can get student account its totally worth it for either cases

my entire shopping is on Amazon. Sometimes, I go to store, but end up buying stuffs off Amazon.. , there is a huge price difference anyway.. some of the items gets expensive on Amazon, coz few sellers normally don't keep up with the pricing and old price may still be lingering, some unfortunate may end up buying those stuffs on old prices. Other than that, Amazon is notorious for keeping price low.

I signed up with them 5 years ago, when they had no Prime Video and there was no taxes. Now, they've Prime Video but hecuva taxes on items you buy.

Btw, your amazon prime is only for Prime eligible items, not all sellers are prime eligible, meaning you still have to pay for shipping etc for those non-primes.  Ever since, I always make sure I buy items by seller as Amazon only, any other sellers is rare chance for me.

If you are not a frequent buyers on amazon, I don't think you need to sign up with them, but if you buy more often there, 79 bucks a year is nothing. It's like 20 cents a day.

I highly recommend Amazon to everyone though and think it's very much worth.

 Amazon Prime is totally worth it if you buy a lot of things online. If you are a student, I would definitely start with a student membership at $39 a year for one year. Otherwise it is $79 per year. The free two-day shipping is awesome and most things are cheaper on there. It's really worth it if you buy a lot of books and electronics.
