Broken Glasses

While I was in Fort Worth, I could feel the right earpiece on my glasses start to work itself loose. Last night, it fell off completely. Lisa taped it back together with electrical tape, and it's holding together for now, although now I can't fold the glasses shut. The break is not in the glasses frame itself, but in the earpiece and where it joins by a screw to the frame, so it's probably pretty easy to fix. The question is whether I want to stick it out until I get back to California in two weeks and take the glasses back to the place that sold them to me in the hope that they'll fix it for free, or go to someplace local here in Oregon and pay for the repair.
