GT has provided a range of free forms for use with Mal's cart. This is a variation based on one of them.

T Shirts with different sizes and colors, plus a quantity discount on T-shirts. Up to 9 cost 2.00 each, 10 - 30 are 1.50 each, and over 25 are 1.25 each.

$1 is added for a Medium shirt, and $2 for Large. These additions are NOT discounted.

The customer can continue shopping and any matching specs, e.g. Large Red, should be combined. He can also change the cart contents but warn him to make sure that the total number of shirts matches the details.
