My GF used these last time, very easy and worth the $100 if you can pack and unpack in a week.
- The boxes are super strong so you don't have to be as careful when packing
- Since you're not being as careful, you can pack a lot faster!
- The boxes stack, so easy to move, especially on the dolley
- The wardrobe boxes are kick@$$ for moving all your nice clothes, throw shoes and stuff in the bottom too!
I've moved on the cheap many times before by stealing boxes from recycling dumpsters behind Staples, and never will again. These were so much easier.
