Postcards

I love to send postcards to my nieces and nephews, friends (aka. personal references), and business associates (aka. professional references) when I travel. It wasn't that long ago that one could pick up local picture postcards at every gas station and drug store. Nowadays, it takes quite a bit of searching to find postcards. I will be flying to Atlanta on 11/5 for a job interview in Rockmart on 11/6. I've used Zazzle in the past, but, quite frankly, I think their shipping costs are excessive and turn-around less than desirable. I'm wondering if any one can point me to some where that they KNOW carries postcards that I can pick up once I get into Atlanta at 6:30 PM. Better yet, I'd be very appreciative if any one could get me some postcards before I leave for Georgia that I can get written before I leave and need only drop in the mail once I get to Atlanta. Leads much appreciated!
