Go to the meat department at Walmart around 11 am. They have awesome boxes for packing, especially the tyson ones. They're strong, have hand holds, clean & free! You can usually get enough in 1 trip or hit multiple stores! Any day of the week!
We moved my Granny last week & also bought Christmas wrap for 10 cents a role to use as packing paper! Cheapest move ever!!!
