Free shipping is offered on USA orders of $100 or more however, the order must fit into one USPS Medium Flat Rate Box if the order will not fit into one box the difference will be invoiced. As a small business I run a very narrow profit margin and the out of pocket costs for shipping makes it cost prohibitive for me to pay for more than one box.
As of 3/2/2019 I no longer offer International orders directly through my store. If you would like a shipping quote please contact me, I will need a list of the items you are interested in and your full address. DHL adds a fuel surcharge, a fee for residential delivery and insurance coverage is also extra. DHL packages are not insured unless protection insurance is purchased. I cannot cover the customs fees and have no idea what those fees will be when I get a shipping quote, those fees are completely separate and will be billed to you.
