I send Ecards. No postage necessary and no card fees. Plus, most cards are poorly written now and you can customize things. Not to mention gas money driving too and from the store. Online banking. Again, gas money. Skype, as long as both parties have the necessary equipment, no long distance charges, although I don't pay long distance with my FiOS phone, but that doesn't work internationally. Skype will work world-wide for free. I never buy blank CDs/DVDs to write information on, considering I can save data to my phone or E-mail. Plus, USB Flash drives (not JUMP) are way more efficient, particularly on public computers where users are prohibited from installing any software (drivers, viruses, applications, etc.). They don't break like a disc can, but the tips can bend if you aren't careful, plus you can rewrite at your own dispose, unlike CDs/DVDs. Not too sure about that second hand thing though.
