I wrote addresses out by hand for my RGBY group buy, and I'll never do that again. For the extras sale I bought a 100-pack of Avery labels for < $10. There's a web app at avery.com with pre-built templates for all their products. It's not fantastic software, but for pasting in addresses it worked fine. Prints directly from the web browser. The hardest part was figuring out which way to load the label sheets into the printer.
