A hardware store generally sells roughly equal numbers of Maxlast brand hammers and Styron brand hammers.
Given That ...
This store usually sells about an equal number of Maxlast and Styron hammers, and given that last all the Maxlast were put on sale and in a display case just inside the store entrance.
How Can it Be That ...
The Styron hammers (at their usual price and location) sold slightly better.
Evaluate / Goal
We're essentially wondering, Why was it bad for sales of Maxlast, to put it on sale and put it near the front? or Why was it good for sales of Styron, to remain in their usual location (with all the Maxlast hammers moved elsewhere)?
Maybe the sale price seemed to good to be true so people didn't trust buying a Maxlast (they paid more for Styron thinking the higher price indicated better quality).
Maybe the display case was ugly, or people were turned off that they couldn't touch the Maxlast's and see how they felt in their hands.
