address labels?

I think you can have the printer print the return address on the envelope for an extra charge.

I used return address labels I made myself for my Save the Dates but I won't be using them for the invitations. I'll have it printed on the invitation itself.

If you do want the return address labels, they are really easy to make using any graphic arts programs like Print Master, Print Artist or even in Word. And you can download cute wedding related clipart through Microsoft.
