I have 9 sets posted. 7 of the posts would ship for $5.80 each. The houses, I'm not sure about (I have to check the dimensions), but if you got multiple sets, I could ship them all in the same box.
I will bid for as many as I can and see what I win and then maybe you could mail in one box and I am very new at this so please if I win let me know how I get money to you for all the shipping and prices
