It was suggested that we try another browser, which I did and the same situation prevails. I can only buy one image on this special sale - I am a web designer and the client is going to pay for his photos but I don't want his credit card to become the default for my account. If I have to buy one at a time - does the next one automatically get charged to his card or can a choose a specific card for each one?
Are you getting any specific error message while purchasing multiple images?
