▶ How to use this calculator
Daily deal prices can sometimes be found beforehand, for example, from the Sims 3 official forums on the Daily Deal thread (Store General discussion), in case the daily deal list is repeating.
You can find the full price and the normal Complete Your Set price from your store account while viewing the item page. Below are examples of the numbers you would use:
Example of upcoming Daily Deal price for a set I want to purchase. Red circle shows the number I should write into the DD price box (the first one).
Actual set I am interested in. From here you get the other required numbers.
The first price is the normal price before any discounts. Second is your normal CYS price.
This is how the numbers should be put in the calculator. The result means that it would cost me 248 simpoints to purchase this set through the CYS once it is on the Daily Deal.
You can also see what kind of discount Daily Deal should have for you to get your set for free. This is great tool for those who are considering buying more individual items to bring the CYS price down.
