I have never used Light Impressions, but over the time I have been in APUG I have never seen a kind word said about them. If you are a member of APUG you should know to never waste you time or money on Light Impressions.

If they have not shipped after 30 days, contact the credit card company by mail and cancel the charge. If enough people do that then Light Impressions will either get the message, which I doubt, or they will accelerate going out of business.
