Do you prefer to eat out at restaurants or to eat at home ?

I prefer eating at a restaurant to rather than eating at home for a couple of reasons.

First of all, eating at home costs more money than eating at a restaurant.

To be specific, I need to buy all ingredients at the supermarket to cook at home. The ingredients, such as a vegetables, a meat and other things, are so expensive these days.

Surprisingly, after combining the total amount of receipt, the price from the supermarket is was third time three times more expensive than the one that from a restaurant.

[또는 I was shocked to notice that the amount of money I spend buying ingredients was three times more expensive than the money I would use at a restaurant. ]

Second Secondly, I don't have a lot of time to cook. I have to spend most of time on my studies.

If I had to set aside a lot of time for cooking, I'd become stressed out. 

Finally, I live by myself so it's too hard to consume the food at home.

For these reasons, I prefer to eat out at restaurants.
