Re: IDEA: Method for Shopping Cart QUANTITY DISCOUNT?

switch ($num_of_widgets) { case 1: $total_cost = 10; break; case 2: $total_cost = 18; break; case 3: $total_cost = 27.50; break; case 4: $total_cost = 35.33; break; case $num_of_widgets > 4: $total_cost = 40 + (($num_of_widgets - 5) * 5); break; default: // Error $total_cost = 0; break; } This would means the $total_cost is just that, before taxes of course but $num_of_widgets is the quantity.
