There is a Shipping Calculator on the basket page! Just add anything to your cart and click "Estimate Shipping" there in the middle.
Sometimes that doesn't show all the available shipping methods though so continue through checkout to know for sure, you are not obligated to buy anything by adding it to your cart!
Please note that the shipping prices shown the are as close as possible to the actual prices it costs us to ship your package. In some cases there will be a little extra for packaging materials or whatever but in most cases we don't make any money off shipping -- we make money by getting you hooked on our rad things for the rest of your life.
