When selling a series of books online, is it more profitable to sell them individually or as a set?

In personal experience, I’ve found that selling most things individually on eBay will get them sold more quickly. I’d recommend selling that DVD apart from the graphic novels, but making sure that you keep the graphic novels together as a package item. By series, at least.

Thanks, @Akiora! I’ll keep that in mind.

When I’m buying a series that I don’t already have, I try to find it all together so that I have all the books and I don’t have to bid on multiple auctions. So if you are trying to appeal to someone that doesn’t have the series, having them all together would be best. If you are okay with people just buying the ones they are missing, you can do that as well, but you may not sell each individual book as quickly. I would look to see if there are any other listings for that series and see how other’s are selling them when you go to list them. I’d keep the DVD separate so you appeal to people that have read the series as well as people that just want the DVD.

That being said, what series is it?

@Seaofclouds It’s a series called Pet Shop of Horrors. It’s a 10-volume manga series and they came out with a 3-episode OVA too… The OVA was kinda bad though. :P

@ParaParaYukiko Ahh, ok. I’ve read those before. Good luck selling them.

If they are extremely popular and, when you do your due diligence, the books are selling quickly and well, it would be more profitable to sell them individually, in my experience. This involves more work and time, however, and as @Seaofclouds says, you might lose the market of someone who wants the whole series. But conversely, selling the entire set you would not appeal to those who have already acquired part of the series. I’d guess that would be a bigger market.
