To all you non-graphic-design-savvy brides on a budget, what are you doing about invitations?

Just like almost everyone else, I'm planning my wedding on a budget. My wedding is October 20th, and I still have no idea what to do about my invitations. Places like Etsy and Wedding Paper Divas have really awesome stuff but at a not so awesome price (better than the local stationers of course, but still pricier than I would like). I wouldn't know the first thing about making my own on my computer. I'm not looking for anything crazy, just a pretty invite with response card plus envelopes. So what are you ladies doing? Any ideas?
