The Home Store

The Home Store, similar to Buy and Build Modes from The Sims games, is one of the places to buy various items for the Sims' houses as well as customize the walls, floors, etc. of the said house. It also includes an inventory that allows for the storage of items.

The Home Store can be accessed by clicking the picture of a chair next to a lamp in the bottom center (larger device) or the bottom-right corner (smaller device) of the screen while at any Sim's house.

In the Pet Update, there are names under the items of the products in the Home Store. This makes it easier to find certain items one needs to complete certain quests. As of the 2017 Penthouse Update, there is a new category called "New Items", meaning whenever they unlock items it will go straight to that section instead of going to the inventory.

Additional Information

As evidenced by the pool update, it is possible for the Home Store to continue to expand.
It seems that the items available in the Infant, Toddler, and Preteen categories are the same as those available in the Children's Store.
Interestingly, rabbits are available in the Home Store, as opposed to the Pet Store, where the cats and dogs can be bought. The Infant, Toddler and Pre-Teen tabs are only available after the children's store is brought.
New items are unlocked when one levels up.
To access pets from the home store, one needs to click on the Pets Tab. However, they must build the Pet Store first if they want to gain access via home store.
Sometimes, there may be sales of certain items, even if there are items that temporarily stay in the store for an amount of time.
