If/when you have kids it's great. You pretend you're getting it for them: "Boy, i bet the kids would really enjoy this Biggs Darklighter figure. Afterall, we... er... they don't have one yet."

That's what i used to do to justify the impulse buys. Fortunately for the family my impulses were very small in scale. I say "used to" because the kids aren't into the Star Wars stuff like they once were. They inherited all my original toys, and we certainly had great times playing "Star Wars". But, they are girls and are growing up and have found other things to occupy their time and interests. They still LOVE the original films, though. :D
