I did order some new business cards from www.inkgarden.com for my Pampered Chef business - they are SUPER cute. I was able to design them myself - I think I'm going to love them :)
InkGarden is having a sale right now - 100 FREE business cards - Use codes100FREE for one sided cards and 100FREE2 for two sided cards. These business cards are free, you just have to pay a shipping fee of $4.99.
Even if you don't need "business" cards per-say you could always get some personal cards - just so you have your information handy, OR you could get Mommy cards that say something like "I'm Jack's Mommy" etc... OR you could create some really CHEAP valentines like these ones:
