So, what do you pretty much have to have when you move?? Boxes, right?? Everyone needs boxes to pack their stuff in, but how do you get them without breaking the bank??
Simply ask for them. Grocery Stores, Auto parts stores, and ABC stores. Grocery stores usually have some of the larger boxes, parts stores are going to have mostly medium and small (think motor oil container size), and ABC stores are going to have medium to small, but most of their boxes are really sturdy. They have to be to hold all of those glass bottles.
So, to prevent paying for moving boxes, start collecting them a few weeks before you plan to move, that way to be sure to have enough.
