Prices increasing, product quality decreasing?

I recently got hired at Wal*Mart in the Lawn and Garden section. I've been selling a lot of highly expensive grills. They're all name brands. It seems like every other hour we are getting them back due to the grills being poorly constructed, made of faulty materials, and over all shotty craftsmanship. I went to wheel a grill to the register for a customer and as soon as I went to move it the wheels snapped off and the grill came tumbling down. The plastic broke that was holding the wheels to the grill. Today, no one was even near the grills and a grill just collapsed on itself. The plastic support system just completely buckled. The funniest part about this is, the grills are more expensive this year then last. Last year they didn't have this problem.
