selling prices, S$/$Q ratings, and number of models$/$styles offered$)$ In determining company sares v particular geographic region is false?

Tiny cross$-$company differences on a highly influential competitive factor $($like selling prices, or S$/$Q ratings or models$/$styles$)$ nearly always have a bigger impact on company sales$/$market shares in a region than do large differences on less influential competitive factors like mail$-$in rebates or expenditures for retailer support.

Big company$-$to$-$company price differences in a region weigh heavily in accounting for company$-$to$-$company differences in branded pairs sold and market share in all four geographic regions.

In the rare instance that all companies should happen to charge the same wholesale price to retailers in a region and the same online retail price at their websites, then price becomes a total competitive inonfactor and has zero impact on buyer appeal for one company's brand versus another.

How much company selling prices matter in determining each company's unit sales$/$market share in a region is not a fixed amount but rather is an amount that varies from "big" $($when price differences are also "big"$)$ to "small" $($when prices differences are "small"$)$ to "zero" $($when the prices of rivals are identical$).$

As the spread between the highest$-$priced company and the lowest$-$priced company becomes smaller and smaller, the weaker is the unit sales$/$market share impact of the price differences among competing companies.
