More information tabs within a post?

Is there a way to modify my singlepost.php to include a couple ‘tabs’ such as “Specifics” and “Reviews”? I’m trying to get the look of, for example, when you are shopping online and there’s a product with the bare details and price and then there are ‘tabs’ under it that are clickable to offer more info on the product.

This way I can get more products neatly on one page.

:o) Thanks.
