I was about to say "a charger for $14," but that's not the case anymore. All in one purchase, I bought 512MB of RAM, a #00 screwdriver, and a 512GB USB stick for semi-regular backups. All three only cost me $30, but I never got the flash drive. I think my grandma might not have seen it when giving me my mail.
I did get the RAM just fine though, and now have it installed in my laptop, bringing it to its total potential of 640M. It doesn't feel insanely better, but that's due to my benchmark being the seemingly atrocious version of The Sims, despite that game being originally programmed on Mac OS. At least while downloading files, my total free RAM is 230M, not 3M.
