Get a sewing machine, go on a zip replacement course and do it yourself. I have never thrown any clothing away because the zip was broken.
I am not a brilliant sewist, nor have I yet done the course but I will be signing up for it as I am struggling with replacing a zip in an expensive anorak. But throw away a jacket that cost about £100, 7 years ago because the zip is broken - Never!
