Epic Problem

So I've been planning on buying this laptop. It was 461 dollars (including tax), because it was on rollback. WELL, I went to look at it today (i just had it sitting in my cart, cause i'm waiting to have enough money to buy it) AND IT'S OUT OF STOCK. So I found another, except it's gonna be 40 dollars more. I need to figure out how I'm going to afford this.
