I think you can find all the sweeps listed on SA, but the question is really about how selective you are.
Some people who enter 500+ per day have a broad range of interests as well as different age groups in their immediate families. For example, they enter for baby and toddler items, teenage items and adult items, including entertainment, sports, trips, electronic and household things, books, DVDs and CDs. Other people have lots of grandchildren or use their winnings all year as gifts, or save them for Christmas, so they also enter all kinds of sweeps.
People often post that they only enter for things they can use. If you have a smaller household, no young children, or you are not a sports enthusiast, that would already reduce the number of sweeps you enter.
There are some regular sweeps with multiple sweeps but few winners. If you choose to enter them, that would also greatly increase the number of sweeps on your list.
The sweeps are here at SA and if you just want to win, it is easy to find over 500 sweeps to enter. If you want to win things you really like and would use yourself, you would probably end up with a much smaller list, but one tailored to your personal interests.
:wave: I enter 500+ a day from SA. If you go to the new sweeps daily and add them to "My sweeps" it isn't hard to find the ones you want.
As pmeek said, you can pick up lots of new sweeps by adding them from the new list every day. If you want to catch up or have a look at sweeps you may have missed or skipped, one way is to pull up all the sweeps in a particular category, like Daily, or Books. Another way is to search by prize. I always seem to find things I overlooked when I do it that way.
What I am trying to say is, the sweeps are here, but it is not just about numbers.
