Greetings!
Shipping costs are based on weight and dimensions and destination. I base my shipping costs on https://postcalc.usps.com/. Upon request, I can unbox the set which is often cheaper especially for larger sets [NOTE: unboxing is removing the contents from the Lego box and putting them in a new box, and not shipping the Lego box]
Please, please, please ask for a quote, it might take me a few days, but I'm glad to get you a good quote. I take purchases as a serious contract. If you click buy, I'm expecting you to also click pay.
Please ask questions, I'll try to answer them to the best of my ability.
Thank you.
