Google does not look at how expensive or cheap your products are for organic search rankings. They don't rank better deals higher in the search results. They don't downgrade the rankings of rip offs either. The price of a product has no direct bearing on the organic rankings of your web page.

Pretty straight forward, no.
Of course, with Google Shopping, which is paid, you can sort by price.
