1. Check Your Order's Weight
There are some sweet spots that provide better rates

70 lbs is a "magic" number:

1. A package that's as close to 70 lbs without going over gets the best rate-per-pound.
2. An order that goes over 70 lbs gets a better rate-per-pound as it gets closer to 150+ lbs than it does 71 lbs.
3. The highest shipping rates occur 1 to 5 lbs, and 71 to 79 lbs

2. More Wood = Better Shipping Rate
Most of the time...

Since wood is dense, heavy, and awkward, shipping a quantity of 1 or 2 (board feet, pieces, etc.) usually carries the highest shipping rate-per-pound. It's more economical to buy a medium quantity than it is to buy a small quantity of 1 or 2.

To see for yourself, add a quantity of 1 to your cart and check the shipping estimate. Then, change your quantity to 4 or 5 and run the estimate again. You'll see the shipping charges only slightly change with a higher quantity of wood.

The 70 lbs "magic" number mentioned before plays a role, too. If you go over 70 lbs, you'll get a better rate at (for example) 130 lbs than you will at 72 lbs.
