How do I list different sizes of the same item?

[jsbabineau]

We sell a lot of chemistry for film developing and other things. Products are sold in quarts, gallons, 5 gallons and 10 gallon containers. How do I list the items without having to list a seperate line item for each size? If it were just sold by the gallon (no quarts) I could have price breaks at 5 and 10 but that also does not work because some people like to buy 10 in the gallon size and not the 10 gallon containers. Any help would be great.

you should use the components, attributes and choices as this is the way to get your drop down boxes.

It is all in the documentation
