We've moved 4 times, 3 for work related (out of state) moves. We save receipts. Hubby said something like receipts either 6 weeks before a move or 6 weeks after a move can be used, can only do before or after, not 3 before and 3 after. We had lots of friends help, we bought pizza and beer, saved receipts and we could write it off. We also invested in totes.
Taped on the outside what was inside the box, remove info after move and they are reusable. Wheeled also, great for kids going off the college. We have a large shelving system in our basement and now use these totes to store toys, holiday decorations and my husband's collectibles and even some camping equipment. Tax write off for us.
If you go to a place like uhaul or another moving company, they have garment boxes. That is the only thing I would make sure I purchased from them. They are large boxes, like refrigerator large but not as tall and they have a bar going across. All your hangable items go in here, they seal the top and it's just so easy. I think they are like $11 from the movers/uhaul. The night before each move (out of state ones) we loaded up our cars with things we needed to keep with us (dog food, cat food, change of clothes, baby diapers & wipes, portable gaming systems & games, etc.). In the morning the kids would get washed, eat and go and play while the movers did what needed to be done. Because of totes, this last move was about a 1/4 of what the first move was. The movers get paid to pack, the more boxes they pack the more they make and the weight also plays into it. We learned this after the first move when they refused to use my original boxes, with all packing materials, for my stereo. They said they would pack the stereo in their boxes and the boxes in a box. I think they charge by the box and they will take the boxes with them when they unload and use them on in town moves, don't think they credit those back to you either (this is what I was told by someone else, not entirely sure if that is true or not).
If you get the garment boxes, save them, great for hanging off season jackets and keeping them stored.
oh and keep track of the cable remote. Neighbors were moving and all of the sudden couldn't find the remote. The packers packed it. Luckily we had an extra, gave it to them so they wouldn't be charged for the remote.
