I just got a fresh bottle of Ivomec Eprinex. It's the 250 ml (8.5 fl. oz.) size and waaaay to much for my small flock of 9. If you're interested in splitting it with me, let me know. Here's a link to it at the manufacturer's website: http://ivomec.us.merial.com/cowcalf/products/products_eprinex.asp. Expiration date is 6/09. I paid $41.95 total, will gladly give you half in the original packaging for $20. E-mail if interested. Thanks!
