I came into possession of over 300 EF-23 24v flasher/turn signal relays made by CEC Industries, all brand new in their boxes. I've listed them on Ebay and sold a few of them, but i'm wondering if anyone knows of any other outlets to sell all of them at once or at least sell them in bulk?

Here is an amazon link to what I'm talking about (I would share my Ebay listing but I'm not sure if it's allowed or not):

If anyone has any ideas I would be truly grateful. Thanks!
