i won't say anything regarding the morality of a deal one way or another. i'll just remind the people who object to certain deals that you do have tools at your disposal -- namely, the telephone and e-mail. if a deal offends, and one wishes to prevent said deal from existing, one can always call the corporate offices (or e-mail them) of any retail chain and level your concerns with them. i'm sure they'd be very appreciative and would probably take the necessary steps to ensure the deal is quelled as soon as possible.
this is not in reaction to any specific deal. just a gentle reminder that those who have moral objections to a "deal" don't necesarily have to sit idly by and watch it evolve in silence.
Being cheap doesn't mean you have to be a liar and a thief. Have some respect for yourself.
