I too prefer a checkbox over an "add to cart" button for several reasons.
When shopping the "Bread" aisle for example, we usually pick 2-3 different
types.  If you leave that aisle and return later, the boxes that you checked
previously are still checked - giving a proper reference.  It allows you to
easily remove an item selected previously rather than clicking a "remove"
button.  On the checkout form, you can easily adjust your cart to match your
budget.

Right!  Any valid link on the page actually updates the cart - which took a
little planning to implement.

Good point.

Good suggestion.

Good suggestion.

I considered that.  The actual super market I used for a model never had
more than 30 items in a category, which seemed like a reasonable number to
download at one time.  But page navigation may be required in some
situations.

Very good comments.  Thank you.
