Costco is good...are you talking about many cards of the same print or one or two of the same? Different choices for both. My local Walgreen's has 10cent Wednesdays where each print is only 10 cents. I then buy nice cards with envelopes (got them at an art store, but think you could find them at Hobby Lobby or Micheal's and use a coupon). The blank cards come with double stick square for attaching photos. The cards seem pricey, but they are nice and yu can send them/sell them without being embarassed. Plus, they're a lot less than commercial cards these days. Good luck and enjoy Florida's great scenery!
