I'm not entirely happy that certain sellers will take ONE item (eg. a collection of prints) and split it up into component parts to sell. It's just unethical for them to try and make a larger profit, especially from people who don't know that these items should have come in a set (it isn't just that they should be worth more in a set, but should unknowing buyers pick up just one item, they'll be annoyed if they find out they'll have to find the others separately and probably won't have the case/box the original collection came in. (hm...why do I care when it's likely to be mostly ignorant newbie fans - the type that annoy me when I see them attempting to cosplay with US pronunciations of character names - that fall for this kind of trick?)
Yes, this was a selfish rant. I spotted that seller sometime last year, and would love to broadcast to everyone that they shouldn't buy from there. Lucky for me, I found someone else with the Hisaya Nakajo Best Select Art Collection, and am quite happy with it now that it's arrived. It's just that I'm now curious about the collections of Yamada Nampei, Odagiri Hotaru, Mizuki Ken and Takemiya Keiko. I especially want the first of those... Maybe I should email that seller.
