For the record, buying something with the intention of using it for some time and then returning it is considered ????, since you are making use of the seller’s property because he is holding your money, which he will need to return. If the seller is ???? ???, this is a serious ?????.
Without question, most Orthodox Jews are horrified by the thought of such practices, which are in direct opposition to Torah and Middos Tovos.
Nevertheless, the fact that there exist those who perpetrate them should give us pause. How can we better train and educate ourselves and our children so that the exploitation of such loopholes, which is ??? ????? ????? at best and outright ???? at worst, is not perpetuated?
