To add on, I still do not feel that MyPoints, Tupperware, etc., should treat customers like criminals because they took advantage of an offer that made no economic sense to these companies.
I would like to compare this to a homemaker who would spend her (or his) time collecting coupons and researching things like double-coupon promotions at local supermarkets. Then they would go to the supermarket and buy $500 worth of merchandise for 10 cents, after combining all the coupons and offers. Does this make this person a criminal, since they took advantage of the system? Obviously, the supermarket and product manufactures all lost money on this, for taking advantage of a discounting system in a way that it isn't intended. And when this happens, you may see such a person (using all these coupons) written up in a local newspaper as a hero! But with MyPoints and Tupperware, we're treated like murderers for doing something similar.
Anyway, I had to get this off my mind.
