Ghassan, I never heard of Celance, but Permax is the brand name for pergolide mesylate. You may want to check out Athena Rx Home Pharmacy, a division of Athena Neurosciences, Inc., phone #1-800-528-4362. As of 11/94, the price was $69.97 for 100 tabs. There are volume discounts (e.g., 200 tabs...we're speaking here of the 0.25 mg....was $126.23). Athena sends via FedEx to your home at no extra charge. Plus, they have a refill reminder service. I just recently started buying from them because the prices beat what I was finding elsewhere, and they gave me a 10% discount on my first order as a new customer. I have no affiliation with them, so this is not a paid announcement--simply an information-passing-along thing. They carry Eldepryl, Sinemet, Atamet (which is the generic Sinemet), Parlodel, and I don't know what else. Hope this helps. Marti Eiermann
