Because a shopping cart page is usually designed specifically for the
intended use, a generic shopping cart implementation may not be too
useful.
Basically, a shopping cart can be implemented by declaring in your
Session class a NSMutableArray instance variable with appropriate
accessor methods ... This isn't difficult to implement in WO.

You know just about every WO newbie asks this cart question. And just
about every time the answer is the same:
It's really easy! You just ...
Now, personally, I agree that it's easy (having done it). 99.99% of
the effort in making the shopping cart
is in getting it to meet the desires of the people asking for the cart.
But I also watched a senior engineer
struggle with a cart for over 2 months. Part of it was that I gave him
a framework that did all the validation
and database work. He spent at least 4 weeks trying to understand the
validation logic. To me it was strange
because it was
instantiate one of these do addOtBSoRwK, instantiate one of those do
addOtBSoRwK, etc.
save it and catch the validation errors and make the user do it right.
But he didn't get it. So now I'm not too sure that it is as easy as we
all know it to be.

All that hot air being vented is it really as easy as pointing the
newbies to WOPetStore?
