i can't afford it either, . i did the hardest thing, I saved a tiny bit each week, every bill i would handle over a 10 spot would get put away, i did without, food, beer, fun many a night just to save that 20 bill, or 50 bucks. I saved for about 4, just under 5 years this way.
took me a long time of agony of saving, but in the end, when it was time to shop, and my purchases FINALLY showed up, it was a magical feeling.
