I have found the best way to get an extra 10 LPs each time is to get all your sims doing something, planting, cooking, goals, working, school, or sleeping. Then close the game, double click the home button on the iPad then select and hold the game until the red negative appears, then click this to completely close the game, then go to settings on the iPad, general, date/time turn it off and change the year to 2013, then go back into the sims game and collect the plants etc, and you will notice an additional 10 LPs appear. If any of your sims are frozen just change to another sim or map then back and it will unfreeze to collect all money and xps. Once all has been collected completely close the game again with the red negative then go to setting and change the date/time to on. You can then set all the sims planting etc again and collect another 10 LPs, as above. I have over 300 LPs, but don't spend all day doing this, but have robbo cats and dogs and all the lp houses, so have been on a spending spree.
