Is There a Cap to the Number of Champion's Seals You Can Have?

I ask becaude I am sure on Saturday I had 246 to spend, I have done my dailies every day and now I check and I have ... 246 ???

If I have done those dailies for nothing I am going to be PISSED off!

Update: Well, I hust handed one quest in and I am now at 247, so I guess not. But I am still sure I was already at 246 days ago :S wierd!
