Shipping starts with a flat $2 base fee, and each item adds an incremental amount. This way if you buy two posters or books, it doesn’t double the shipping fees, it just stacks a little bit onto the shipping total. The extra $2 amount will show up in your cart. It’s not ideal, but it’s the best way to avoid gouging you folks on shipping fees.
I offer Standard US, Canada and International options, as shown in the dropdown for each item. I only ship to Earth (sorry, MIR Space Station).
