Houses are a one example. Suppose you're looking at buying a house that's $200k. Then assume that you live in a deflationary environment where all goods get cheaper every year, say by 10%. The immediate conclusion is that in 1 year, the house you want will cost $180k. If you can wait 2 years, $162k, and so on. So while you may eventually buy as the house still has utility, you are likely to delay the purchase as long as possible to avoid losing money to deflation. (The opposite of this scenario is housing inflation, and causes people to buy houses sooner and for more money than they would ex-inflation. This makes some sense if the inflation continues as buyers expected.) This scenario is different from single goods getting cheaper every year in that when the prices of all goods are going down, it's very clear that the value of money is also going down. Deflation slows spending primarily via expectation of future deflation, so across-the-board price declines will have more impact transmitting deflation expectations than mixed signals (electronics down, oil up).
