My favorite place to order Kodak prints from my digital shots is Ofoto. They are having a bunch of specials right now, so take advantage if you need to order a bunch of photos of…say…your niece.
I presume the discount coupons could be used on two different orders. (You can generally only use their coupons one time, so make sure to get the most for your money.)
I've tried them all and swear by Ofoto.com. Go try 'em sometime if you haven't.
