Funny you mention garbage bags
garbage bags i use Hefty. ziplock bags i use Target brand
laundry detergent and baby wipes i also don't mind Target brand
another thing i (used to) spend extra is diapers. i don't care HOW cheap or even free Huggies are. they just don't come close to Pampers
i also only use Palmolive dish-washing detergent and only drink Poland Spring bottled water.
