Item is LOCAL PICKUP in North Tacoma. Because people outside of Tacoma, Washington do keep buying and are unable to pick up which results in needing to cancel and relist the order, I am offering a shipping option. The shipping cost is a flat rate as it is 2 boxes of blocks, so I can't do the calculated shipping.  I based it on the shipping rate for the farther distance in the United States. If you do choose to purchase with shipping and not local pick-up and the shipping is cheaper to your location, I will refund the difference in cost if there is any. However, even local shipping is incredibly expensive for the weight and dimensions of the boxes. Please only choose local pickup if you are able to pick up the blocks in North Tacoma. The preferred location for pickup is the Starbucks at North 26th and Proctor.

I will only ship to the continental United States. I was unable to remove the EBay International Shipping from the item and the exclusions section was not working. However, I will need to cancel any orders outside of the United States because of the prohibitive costs of shipping and the inability to calculate the cost of the 2 boxes.
