Did you know that every time you click on a product to see it's details, an entry is recorded in the "recently viewed list". It is quite handy when you've spent some time on the site browsing many products and want to go back to the one that caught your eye before. If you really like the item it makes sense to save it into the "wish list" and then log into your account to save your wish list permanently.
To save your favourite ones in the "wish list" just click on the "add to w. list" button next to the item. You also can add the item straight to your shopping cart by clicking on the "add to cart" button.
Once you leave the site or after some time of inactivity (around 20 minutes) your "recently viewed products" list will be cleared.
