I noticed you noticed we were looking at cordless phones, and I thought you might be interested to know that we actually bought one from you... just a few days ago. So, no, we are not currently planning to buy another cordless phone, even though this is the second time in two days you have e-mailed us about them.
P.S. Some people might think it's kind of creepy if you e-mail them saying you "noticed" their shopping habits. (I may or may not be one of them.) Sure, they know that you're an online business and keep track of that kind of thing, but we tend not to think about it on a daily basis, and when it's blatantly pointed out to us, it feels weird, like some guy's been following us around while we shop, taking note of what brand of cereal and shampoo we buy. Alright, occasionally we find it useful, like when we can just click on one of the "recently viewed" objects on the home page, rather that having to search for it all over again. However, this is not the first time you have suggested that I might be interested in something I have just purchased from you. Food for thought.
