for anyone wanting my work i always ask for a contract up front to see if they exist and what their terms are. if they aren't fair, i don't deal with them. i check the addresses and phone numbers to see where they go. like do the all end at someone's house? check how old their webpage is using a who is - if its' super new, i'd avoid them.
you can ask them which specific works - with a link, and see if they are actually real and not an oil rig scam.
i don't think there is a way to just order things, and they would want a bulk discount. you can use the designer prints site, but you can't control discount at all, and others will get discounts as well. you would have to print them yourself.
