I currently have three completed books, and I'm thinking of doing a box set to help cross-promote them. What are the pros and cons of this idea? And would it be best to offer it for a limited time? My overall profit could possibly suffer, but it could be a new avenue for sales... Any input?

Everything depends on you. Pro: people will surely get the whole saga or collection and probably read your whole work. It will be cheaper for them than to buy the books one by one.
Con: it will be more expensive for you to do it. You will get a lot less money by spending in making the box set and then making it cheaper for customers.
(because nobody would buy a boxset if it's cheaper to buy the books one by one)

Appart from that, you should always have both options for people who won't risk getting 3 books they don't know if they will like.

Good points, Nathalia. Thanks!

I would offer both options: sets and singles.
