My wife went at 2pm and before close in the last 2 weeks.
She said before close was a good time, less people. She did not think they were limiting people in the store at those times.
I've also hit the business center one on broadway avenue. They open at 7am. They don't have near the produce or fresh food that the maplewood one has but you can get in a 7am vs 10am. I'm guessing if you go every 6 weeks you probably want to stock up more on fresh stuff than packaged/processed type foods.
ETA:
My wife said they were out of TP, otherwise stock was pretty good. You pretty much need to be there right when they open up if they have TP. They will usually come out and tell you if they have it right when they get ready to open the doors and it's been my experience that it's usually on a pallet not too far in the store, so that you don't need to do a made rush to the back of the store.
