We only show you with the product information and specifications and the best prices available on different stores, we then link you to the merchant stores where you can actually purchase the product if you want.
By creating an account with us, you will have some added functionalities enabled. Like you can write reviews and comments on products, recommend products to your friends, discuss a product with your friends, etc.
You are not required to create an account with us and the product purchase takes place on the merchant website, not on our website. Our site only displays the best prices on a product and if you want to purchase that product, we will redirect you to merchant's website where you can purchase it as per their terms and conditions.
