I signed up for a free Amazon Prime membership using my college email id. This free membership allows me to enjoy all the "benefits" offered by the Prime membership. However, What I have noticed is very contradictory to the benefits offered by the service. According to the Amazon Prime, certain items are eligible for "FREE Two-Day Shipping". Okay! Good. But I have noticed that the eligible items are actually expensive by $2 - $3 than ineligible. For example, if you buy branded headphones from a "Prime" eligible listing it would cost you $30. However, if you buy same branded headphones from regular listing (ineligible prime listing) It will cost you $25. But then again you will have to pay its shipping price. So how do we benefit from Amazon's "Prime Membership"? Because, no matter which option you choose, you'll end up paying same amount of money. However, if you are not a college student, a regular Amazon Prime membership costs $79 a year ($99 after March 20th). So does it really make some sense to buy such service? Or If I am wrong, please correct me.
