Often the prices online are much lower than in a simple store.
A couple of years ago, I picked out a refrigerator in a store, looked at how much it cost online, and bought it online with home delivery.
Now I bought a phone online, but the TV turned out to be the same price in a simple store as online, so I bought the TV in a simple store.

Also, when I was quarantined with Covid, I bought groceries online three times.
But they seemed to be more expensive than just in the store.
