PRODUCTS

Grade : 10 out of 10
Amazon has a wide selection of products. In fact, they almost have too much variety that it takes a while to see all of them. Having more choices is never a bad thing unless you don't know what you're looking for.
Their product's page lets you see the product in a larger image. You can then zoom in as much as you'd like. The product's page also lists a thorough description, detail information, and customer reviews. They also show you what percentage of customers purchased this item as opposed to a similar item.
You can write your own review. Look at other suggested products. Or, even upload you own picture of the product.
NAVIGATION

Grade : 10 out of 10
Amazon has a couple of ways to navigate their website. There is a dropdown menu at the top. To the right of that, there is a search box. And on the left, there is a another menu.
The dropdown menu at the top lets you see all the categories and you can drill another layer to see the sub-categories.
The search box lets you search within a single category. This helps you filter out things that you don't want in your searches.
The left menu changes as you keep selecting more specific things you want to narrow down. Its very useful because it lets you filter by many things including brand, seller, and price range.
OVERALL LOOK

Grade : 10 out of 10
The colors for the site are excellent. The spacing between products is good and the pictures are of high quality. The pages seem to be endless with so much information. It's hard not to find what you're looking for at Amazon.
GRADE

Grade : 10.0 out of 10
Amazon's average score was a 10 out of 10. It's rare not to have anything negative to say as a user. But with Amazon, you would expect nothing less than a great shopping experience. They have too many products to count and organize them is an intuitive way.
