Does magic find affect what a merchant has to offer?

I sometimes see Rare (yellow) items on Merchants, and sometimes normal (white) items without any stats. This leads me to believe that there is some sort of RNG for merchants for not only the stats on the items, but the quality of the items.

Stacked to 90%, and did 80 checks with 0% and 80 checks with 90% in nightmare difficulty, the appearance of white and yellow items in the town vendors were the same (less then 0.2% difference), granted this is only 160 complete checks, and is a small sample size, but with this said, I'm saying NO, it has no effect on the results.

I don't think it does

I ran through some acts in Hell with 5 stacks of the Valor buff and MF gear on last night, which put me at around 190 MF, and didn't see any yellow items for sale. Based on the increase in yellow items I found with that much MF, I should have seen a few.

I visited vendors pretty frequently too, since I was picking up more blues/yellows than normal with that much MF, and vendor my items when my inventory gets full since I don't need crafting materials right now
