Another survey wasted 10 mins of my time for 25 e-rewards cents. It asked about 20 questions, including a series about which retailers I've visited when looking for internal hard drives. Once it discovered which retailer I actually bought my hard drives from, it finally decided that I don't qualify. (I wonder what they have against newegg.com?)

It was titled "Study about Business Purchases", so you might want to give it a miss if you get that one.
