I have bought sight unseen from a reputable breeder... I only did this about 3 years ago, and it was only the second time I had ever ordered via the internet.
Did the snakes turn out alright? They turned out extremely nice, but they didn't look the way I expected. I was hoping for something a little more vivid what with the way the breeder went on about them, but I was still very happy anyway when I opened up that box (which, incidentally, was brought to my house in a plain white van. It was supposed to have been sent UPS. I don't get what happened there- still a mystery to me!)
Was the service alright? Well... it was a little lackluster in the beginning. Is that too surprising? Someone who is "too busy" to take less than 5 minutes to shoot a picture and then upload and send it, is certainly even less likely to have time for things like answering questions and e-mails.
I was lucky- I found out that the person I had bought my snakes from had been weeks-gone-by slow in responding to my e-mails only due to an accident. When I had some care questions about the snakes later on, I received very prompt customer service that was slower in the beginning- even before the accident.
Although my previous and only experience had been successful, my main concerns now with buying from someone who won't snap picutres are: what else is this person too busy for? Too busy to regularly clean up after their animals? Too busy to do a quick visual exam for health regularly? Too busy help you out if a problem comes up for you? Ifthey just can't afford or can't figure out how to use a camera/computer, I then have to ask, "have they been able to afford veterinary care for their animals if/when they've needed it?"
