Moving Supplies
When people move, they don't spend much time on moving supplies. That's a mistake: how you protect your valuables is key to your move, and making sure you have enough of them will save you a pretty penny.
First off, don't just use second-hand moving boxes - they're cheap, but if they fall apart during your move, the damages will outweigh any savings on the boxes. Also, professional boxes are a uniform size, making for easier packing in a truck.
You also want to ensure you have enough moving supplies, so that you can get everything packed before your moving company arrives, or to save you multiple trip to the store. Get more than you think you'll need - most people always end up needing more than they think.
