With that said though, I am getting ready to hit the "buy" button for some high performance parts for my car in the next few minutes. I wanted to order them a few weeks ago but they run a sale this time of year, so I waited for this very reason. To me this is different because #1) I have the money sitting in my account to pay for the parts
(although I am going to use an interest free offer on my credit card to use their money for nothing for the next 18 months + get a cash back reward/rebate - ya gotta get over on The Man whenever ya can.
), #2) I'm saving money on something that I planned on buying anyway and #3) this is not an impulse buy - it's a stupid waste of money, but it's not an impulse buy.
