I decided to see if it is worth it to buy common household items from Amazon vs my grocery store. These will only include non-perishables.
Baby wipes Winco : 6.98
Baby Wipes Amazon: 7.15
Luvs Diapers Winco : 16.98
Luvs Diapers Amazon: 15.96
Cotton Swabs Winco : .98 Cotton Swabs
This isn't as extensive as I was originally planning, but it has become quite clear very quickly that there isn't much savings, if any to be had by doing some shopping. Gas can't be included into the equation since you still have to go to the store for food anyway. I was initially buying diapers on Amazon just because I assumed it would be the cheapest place. When you assume you make an ass out of u an me. Or in this case just me.
