Can you buy individual photos from Disney photos?

Excuse me, I was wondering if I could possibly purchase individual photos from Disney's photo services? I've seen some great shots of my family and I at the park, and I'd love to have a few of them printed out for keepsakes. Is this something that's possible, or do I have to purchase an entire package of photos? I'd appreciate any information you could provide on this matter. Thank you in advance for your help.
