Hey all - this may be old news to you guys, but a friend just sent me a link to a place that prints your 12x12 LO on 13x13 paper for $2.49 when you order 10 or more pages (plus shipping). It may be a wash financially compared to Costco when you factor in the shipping, I don't know, but it seems like a good option, plus you can avoid the whole resizing to 97% to avoid Costco trimming your LO. Here's the link: http://www.archiversonline.com/pps/pagestogo.asp

Hope that helps someone! If anyone's used that place, I'd love to hear any opinions!

Haven't tried them but why print at 13x13 when you can just get a professionally printing 12x12 elsewhere?

I wholly recommend whcc.com - you don't need to order 10 copies.. single copies are $2.50 each and since you provide the file in the exact crop size (12x12), they don't crop. They print on professional Kodak archival paper with a wonderful lustre finish. I use them for all my professional printing and they are fantastic. Once you try them.. you'll wonder why you ever use a place like costco... Good Luck!
