I guess pathological pattern of shopping is pretty similar all across the products. For those that we buy occasionally, we don’t really bother about them as we would simply make a purchase according to our needs. But, for those goods which we buy as a hobby or obsession or collection (e.g., dresses and shoes, gadgets, or, for me, books), we would be sensitive to deals and sometimes (nay, often) buy things simply because they are on offer and not because of necessity. We would know as well where to find those deals, mark their usual end-of-season sale, etc. And, so now I’m in the midst of trying to resist the temptation of buying Paul Molnar’s Divine Freedom and the Doctrine of the Immanent Trinity which is on a freaking 63% off at bookdepository.co.uk!
