True Value across the lake sharpens them for $12, but Batwing is correct. Just get a new chain for $20 and be done with it. You can pick one up close like Lowes or small engine shop at 59 and 1960 if you want ot save gas. They never stay sharp long after they sharpen them anyway, so new seems to work better. Either that or learn how. I watched the tree guys work on their chans while clearing up some of my mess. I would just mess it up more I think, so that was not an option for me.
If you don't have an extra chain for your saw then buy a new one. Then either sharpen the old one yourself, or drop it off somewhere to sharpen it at your convenience. Here's a post with some links to doing it yourself.
