There are several, I don't now the maximum and if there was one, I can't be certain that it will be there again.

you can get a mail for discount offers by setting mailings for offers on in your profile:

Top right next to your name -> change user profile, then goto newsletter section and use link to edit your description.

Also there can be offers in the pulldown next to your name (offer for you).

But I advice you to set the mailing on and wait for a good offer.

Goodluck.
