And here is yet another method using the two ordering clues with a substitution.
Lay out clues 1 and 5 with the substitution for capellini.
Yolanda > capellini = Margie
mushroom > Angie
Notice that Margie and Angie are in the same category, same side of the relation, and a fixed distance from the left side.
That means Yolanda cannot be mushroom. Wade must be mushroom.
Shriekingviolet has a more interesting approach, and it demonstrates how the onesided "Of A and B, one is C and the other is D" clue can yield extra Xs beside the obvious one.
"A is either C or D" is very similar to its twosided cousin. Just find out what C and D can never be, and apply those exclusions to A.
As SV points out, from the partial solution grid, $8.99 is either Angie or mushroom. From the grid, we see that the intersection of Angie and mushroom also has four Xs that can be applied to $8.99. One of these Xs is "$8.99 cannot be Margie."
