Zipper broke after 2 months

Very disappointed in the quality of the zipper. After 2 1/2 months of light use, mostly around the house, the zipper broke such that it would separate (unzip) from the bottom. I sent it back to Columbia for warranty service, but had to pay over one-third of the cost of the jacket to ship it to them after owning it for only 10 weeks. I think this is pathetic quality for a jacket that cost what this one did. I can't remember the last time I owned anything, including cheap stuff from places like Old Navy, where the zipper did this, particularly on a new jacket
