BOS to Nassau?

[spoon2003]

Any seasoned Boston to Nassau travelers? What is a decent airfare from Boston to Nassau in late August? I found flights for $250pp last week on United but all gone this week. Right now JetBLue is around $300pp, should I get it now or is there a chance of a late summer sale? Not many other options right now, AA and Continental are about the same price but the time stinks.

I've never priced BOS to NAS so I don't even know what is a good price. I'm not looking for the bottom but don't want to pay top $$.

Thanks for any advice.
