I just started posting to SmugMug, there you are faced w/ a million options to purchase. The prints from SmugMug look great, I try not to post anything that wont look good as an 8X12 print. You can go bigger, just make sure it’s sharp. Or you can just buy the digital images and do w/ it what you want. The big watermark in the corner will disappear when you purchase a digital download. There are 3 options (sizes), below are examples...
Low-Res 1Mpix: $5
Hi-Res 4Mpix: $10
Full-Res 12Mpix (300dpi Raw or jpeg): $15
If you order full-res, I will have to e-mial it to you. You really only need full-res if you are blowing it up huuuuuge.
