well easy way is to setup a saving account and put some monthly savings in. Then put them in to some sort of investiment (not sure where but things like GIC or term deposit).
or you can go further and buy a house/condo, then all your "extra" $ will go into the mortgage and you won't have to worry about 克制購買欲. Cos you have NOTHING to spend.

Actually back to the topic, 係呢D situation, I will usually "din" for a LONG time ( like a few months) and then buy it. (e.g. a gas BBQ sitting on my balcony)
