Not to nitpick, but Target doesn't engage in this practice, at least not by corporate directive. Some individual store managers may opt to do it, but they're violating company policy if they do. Target just clearances the shit out of stuff until it sells. Once got a coffee table (original price $150) for seven bucks, even. Also, most Targets have standing agreements with shelters in their areas to donate non-hazardous goods like clothing, toiletries, etc, and even dog and cat food to animal shelters. In my years working there, the only stuff that was ever destroyed was done so because of potential safety risks, i.e. returned light fixtures, broken furniture, etc. Overall, Target is a rather conscientious business; they just don't make a big deal out of it.
