That's way too high for 100mg pills, for 50mg pills you're totally being screwed.
Rx price is a little under $10 per 100mg pill (you can cut them in half), and I've seen them online for say 30, 100mg pills for under $350; you can find specials for less than $300.
Best bet is to go to your doc, even if your insurance doesn't cover it, it will be cheaper.
There are some knock offs and other products that some people here seem to like, but I haven't used them, so can't comment.
