It is ridiculous, i also fell in this trap. I never authorize anything what shoppersdicount, and my credit card is being charged twice $12. at first i don't know what is that from my statement, then i type the internet and found out it is scam. I read through other website, some said that it is from buy.com. Then i remember i bought web cam from buy.com and suddenly a rewards web pump out, i can said that is how my credit card being scam.
