Get two credit cards. I got them easily because I was a student back when I got both of them. And a year later I no longer was a student...3 months afterwards I wasn't one anymore, actually, I think. -_- Wait, it was a year, now that I think about it...I think. Bah, it doesn't matter. Just go to a local computer store and get your memory. I got 128MB for just $75 at one near me. That was really cheap, in my opinion.
well, i am wary of having more than one credit card at my age with my little income. i think i'd be too tempted to start overspending. the memory i was trying to buy is $19, with shipping, it was going to cost me about $30 - for a 128MB DIMM. i love pricewatch. and i had the room on my card, which is what pissed me off.
