Thanks for reaching out and thanks for backing us! Unfortunately our production center is not set up where we can combine orders and ship them out in the same package. Even items that finish in the same month (or are in the grab bag sale) aren't possible because of the packages we actually use to ship our items. We are hoping to find a solution for this in the future, but for now it is all we can do.
Apologies for the separate shipping, but we hope you love the products! Thanks again for reaching out.
