You asked, what the heck is the SAVE button on product pages, why should I save products? Well it's a way for you to create your own product lists. You need an account to save products so that when you login you can access them. You can create as many product lists as you like. You can share the link to your product lists with your friends. The coolest thing about the save button that not everyone knows about is, IF a product you saved goes on Sale, you'll get an email letting you know. So if you don't want to pay the regular price, just save the product to your list and whenever it goes on sale I'll send you an email letting you know about it. You can always change the settings of your product lists so you don't get an email each time it goes on sale.
