Due to the holidays (Happy Yule, Christmas, Saturnalia, Hogswatch, Kwanzaa, New Year, Hanukkah, etc to you!) our shipping schedule will be slightly different.
These are the dates you are looking for:
Saturday December 16: Extra shipping day
Tuesday December 19: Regular Shipping Day (the latest point at which we can be relatively sure of Dutch orders arriving before the 24th!)
Saturday December 23: Extra shipping day. Also the last shipping day in 2017!
Wednesday January 3: First shipping day in 2018
After this all shipping will roll back to the good old Tuesday shipping you're used to.
