How do you merge customer records?

I am analyzing client sales and notice that there are duplicate records, each with sales, for many clients.

How do I merge these records to reflect total sales by client?

I'm also wondering this. Specifically, a customer might checkout twice on our site and use a different email (probably accidentally) so now we have one customer representing 2 accounts. Is there a way to selectively merge those records? And/or is there a way to add a second email to a customer profile?
