I do this all the time, just save records of your purchase so when they get a complaint, you can produce the receipts. Or forward them on completion as proof of purchase.
An even better way, if it's the site I use, have the client do their own shopping. Have him/her pick the images and send you the lightbox then take it from there. They seem to like that, it empowers them with picking the images, and not having to pay you for the time to find them. Otherwise I always use the watermarked comps until they accept the images.
