Perhaps it is even noticed: By default Magento is in Shopping cart window give, how much Each one has in the cart and not how many articles.
This can be annoying, If you have a shop maintains, a chance to sit once more than just a piece and then ordered several more items.
Example:
10 x Articles 1
15 x Articles 2
Now there are two variants of this view at a glance. Either “They have 2 Items in your shopping cart” or “They have 25 Items in your shopping cart”.
I prefer the former version and this one can quickly-if you know where- set:
System>Configuration>Sales>Checkout>My Cart link
Number of items in your cart vs.. Artikelmenge
