Another question, should I sell as a complete set or should I sell separately?
I don't think there is a good answer to that.
Common solutions I have seen are:
a) give a discount if someone wants the whole package
b) list as a package and say in your add that you will sell as separates if you don't get a buyer for the package in 2 weeks
c) list items in separate ads (be sure to mention matching items in other ads)
No doubt, listing as separates will get some money in your pocket the quickest, if that is a concern.
