Sims can get a part-time job in the grocery as a Grocery Store Clerk. Sims can also attend Fishing class for §400, and sell fish or fruits and vegetables in the inventory to the grocery. Sims who have enough money can invest their money to become a partner or buy out the property to earn more money. The cost of partnership is §7,000, while the cost of ownership is §20,000. Sims can collect money from the grocery for §1,000 (partnered) or §2,000 (owner) every week.
Additionally, Sims who are at the top of the Professional Sports career can do advertising deals at the grocery, which will reward them with money. Sims can also hold autograph sessions at the grocery. Vampires can raid the grocery for vampire fruits.
Groceries generate the following red map tag in-game:
All harvestable produce bought from the grocery has a nice quality, while fish has normal quality. Sims can buy individual items or ingredients by recipe. Sims can also save the shopping list for later use, but only one shopping list can be saved. Saving another shopping list will override the previous list.
The price of harvested produce from the grocery is 150% higher than their base values. Selling fish and harvested produce to the grocery has 10% higher value than selling them directly in the inventory. Selling them to the consignment store is more beneficial, however.
Every day, there's 5% chance the grocery will have a sale, ranging from 35% to 50% discount. The sale could last for 1 or 2 days. Additionally, Sims who work as Grocery Store Clerk will have a 10% discount if they work at the grocery.
With The Sims 3: Seasons, on every summer if season is enabled, the player will be reminded by a notification to purchase firework bundles as part of summer activities. The notification mentions that the firework bundles are on sale, but in fact, they're not.[confirmation needed]
