Hey Dan,

so for example if you have lotion

50ML cost 10 dollars
100ML cost 20 dollars.

if you add the 100ML to the cart and view your shopping cart, it will display $20 with $10 crossed out. kind of like the opposite of a product with a specials price (crossed out higher price and display lower price).

also if you could get the image swap on attribute to work with your mod, that would be neat.
