I've now started making all my pages 8x8 and am making books to order through snapfish since they now print 8x8 books which are less expensive than 12x12s and easier to keep. I don't print any of my work since I don't have a good printer so this info. is good in case I decide to buy a printer anytime soon.
Also, I just did a digi-scrapped Christmas card and ordered them through Walgreens. Sadly they only print out their formatted cards but I ordered one so I could see if I liked it, then placed a special order using the card I created for a set of 20 + envelopes. Prices are very reasonable but I had to do it in person and did not have the luxury of on-line ordering since I did not use one of their pre-designed formats.
