There is no limit to the number of sweepstakes you can have in your My Sweepstakes - whether SA or SP.
***HOWEVER - If you have any sweeps saved that run longer than one year, they will automatically be removed. ALL sweeps will only stay saved for one year from your save date, so if you have any saved that run longer, resave them at a later date to ensure they don't drop off.
Your individual My Sweepstakes will tell you the total of active and expired sweepstakes you have saved.
Example: if you go to a specific category, and it says you have 33, but you only see 13, the other 20 are in your expired.
While in any category, look up top, and you will see: Alert! You Have Expired Sweepstakes: Show My Expired Sweepstakes
If you wish to have an accurate account of just active sweeps, remove your expired, your count will then show active sweepstakes only.
Please periodically remove your expired sweepstakes when they have served their purpose, thank you.
