First of all, no spaces after commas.

Secondly, you have the list in the wrong order — e.g. U should go higher up, S and G at the end. It needs to be in descending order of price. And why don't you include T and L if you're going to have S and G?

Thirdly, try splitting up, as others have suggested. Do H and M separately (like you'd do Y and B).
