I had the same situation, and Freecycled it. Plenty of interest, and folks that want it just mix them together, add tints, and use them for various projects. So, either post it here, Craig’s List or Freecycle, and set up an appointment for someone to come get it (maybe put a smear of the contents on the outside so you don’t have to open them again when you give them away).
Donation is a good idea, too. No appointments, no flaky strangers, no hassle, and it’s all gone.
