I think I bought from the same ebay seller you did. I got my sister 1000 for her beardie. 2 months later, she just did a clean out and there were still 600 good worms. She also started trying to breed them, but the beardie didn't like them much, so she listed the rest of the worms, plus a bunch of beetles and pupae for $25 on craigslist and got a buyer within an hour.
