I have this same issue. For me, it has to do with how long I'm gone during the day with school and work and the fact that I have to deal with the buses because I don't have a car.

I simply have no desire to go cart around several pounds of groceries on the bus and then carry them up a flight of stairs when I am often times gone for 12-15 hours a day during the week. When I'm at home, the only things that I have any desire to do is to play my game or stream anime or something. I don't want to do even more work when I'm clocked out which makes doing basic things like grocery shopping, doing laundry, and taking out the trash difficult for me.

If it wasn't for Amazon starting to charge tax in my state, I would just order my food off Amazon prime despite the $5.99 fee to use prime pantry.
