Ross,
Do you really need this laptop? I want a laptop as well, but simply cannot afford it at the current time. Cashing in on a deal is one thing (you got a great price) but you need to know where to draw the line. Before I make any more purchases, I plan on paying off my credit cards which reached astronomical levels earlier this year because of a hot deal here, and one there. I justified these purchases by saying to myself "Hey, I got a great deal... if I need the money I can sell this stuff." But you know what, I never sold the stuff. 90+% of the stuff I bought is still sitting in my closet collecting dust.
I know for a fact you want a house. Buying things like this will NOT help you reach your goal. I'm not trying to act like your mother here, but aren't there more pressing needs that the money could be spent on?
This entire message can be summed up in one sentence: If you have to put it on your credit card, you can't afford it. Credit is supposed to be used as a tool, not as a crutch.
