Where do you print your pictures? Costco, Walmart, or Walgreens maybe? Well before you send your next batch to be printed (especially if they are pictures that I have taken!!!) take a look at where I take my pictures to get printed: MPIX or http://www.mpix.com/ .
They offer a HUGE range of print sizes and options. Their quality is superior and they are a professional shop but they welcome the consumer market as well. They cost a little bit more than costcos or walmarts and they have a $5 shipping fee I think but the quality is AWESOME!
