Has anyone done business with these folks: SundaySoft I came across them when googling lightroom. They also advertise on amazon. They are offering full non-academic versions of lightroom for about half what amazon sells it for. They only sell downloads, which looks suspicious, but they claim updates will work properly. They also state the software can not be registered with the producer for phone support. They claim their prices are very low because they don't sell or ship boxed software, just downloads. What do you think?
