Another, more common example in the United States is car financing. Car manufacturers fairly often offer 0.0% or 0.9% loans for up to 36 or even 48 months on new car purchases, especially for models that aren't selling as well as they hoped. The cars are built, so they really need to sell them since the carrying costs are rather high and the end of the model year keeps approaching. So they're often willing to finance them free or basically free. So should you pay cash when somebody is offering 0.0% financing for 36 months? No, of course not -- that'd be silly. You can take that same cash, push it into a 3 year fixed deposit (called a certificate of deposit in the United States) which is government insured up to US$250,000, earn some interest, and pocket that extra money. Free (or cheap) loans are wonderful when they're offered. Then you just set up your car loan payments to be automatic (so you don't forget one), and you pay off the car loan on schedule, but no faster than on schedule.
