Just a note on contacting your credit card company about Light Impressions. According to my Wells Fargo VISA, you must contact them w/in 120 days of the charge. I was too patient w/ Light Impressions and their "back order" and "check is in the mail" routine, so I'm out $70. Moral of the story: contact your credit card company now.
That's because Wells Fargo are well-known dicks. Citibank ran a chargeback well after 120 days of my LR charge. Of course, Citibank are dicks too, just not as bad as Wells.
