Thank you for your interest. The shipping will vary depending on how many sets you are ordering, but it is specified for each pledge. For 1 set, it is $20 for the US and $45 for all other countries. Please look at the other pledges for details on shipping cost.
I have spent a lot of time researching the cost of shipping and handling via USPS. I even called USPS and Stamps.com for help. Based on the package size and weight, the package must be sent via Priority Mail using USPS within the United States. Shipping alone ranged between $13- $19 depending on the zones. You add on packaging of about $5 and it costs me between $18 and $24. Depending on where you are, I make $2 or I lose $4. I'm not trying to make any money on shipping. I'm just trying to find a fair middle ground.
I can send standard First-Class International Mail to other countries, but that is also quite expensive due to its size/weight and what country it's going to. There is no option to specify different amounts to specific countries. It's just a standard rate I had to put in. So I put in a number that should barely cover my costs for shipping and packaging. In some instances, it may be more than my actual cost. Shipping to the UK, for example, will cost a little over $42 while shipping to Ukraine will cost over $66. Way over my shipping price.
