How to combine two nodes based on common title in Views?
Are you using multiple taxonomy terms field to enable the Large, Medium,etc sizes?

On the Views when you click on that taxonomy field, is there a way to show all fields in one line combined instead of separating them? Then use the Rewriting options so that you display with something like this:

[title] - [Sizes]: [Price]

Not sure if it will work, but worth a try. Experiment with separating out the different tokens and combining them in the Rewriting option.

Oh, what Alex said might work too.
