Quiz

1:

When removing an item from the cart, why do you suppose the query validates the session id of the user against the record?

A1:

Users should only be able to remove their own items.

2:

What would be a reason not to store the price in a hidden field when adding to the cart?

A2:

If you stored the price in a hidden field, a rogue user could change that value before posting the form, therefore, writing whatever price they wanted into the store_shoppertrack table, as opposed to the actual price.
