Someone who is interested in buying something might be pushed over the buy/not buy divide by a good price but someone who hated yogurt would not likely buy even if they were on sale or even free. Someone without a pet is unlikely to buy a case of dog food no matter how low the price. Price is just the deciding factor not the SOLE factor.

I'm trying to imagine someone who gagged at the thought of eating yogurt filling their shopping cart with it just because it was on sale. Strange picture.

I do admit that people who first get an ereader sometimes do go a bit crazy and start downloading a ton of freebies at first until they realize they are filling their readers with a lot of books they have no intention or interest in ever reading.
