Walmart and Amazon are testing same day delivery of products in select US markets. Walmart to Go was first rolled out in Philadelphia and Washington D.C.’s Virginia suburbs. Californians living in the northern half as well as residence of Minneapolis can expect the service soon too. Cost is $10 regardless of the size of the order. Amazon is expected to expand services also. Do you really need same day delivery of something when Walmart is just down the road? If the store was more than 2 gallons of gasoline away then the price would be worth the $10, however, it would be easier to go down the street and pick it up yourself. Maybe you don't want to be seen in Walmart.
