Delivery times depend on a few things, the service your seller or you choose (if that option is available to you) otherwise it's only the service your seller chooses or used). Where the parcel is coming from and where it's going (ie: How far away), and then there are other factors which can cause delays such as weather, and general upheaval in the world. Add to this, the accuracy of the address you provided to the seller (missing, or incorrect details), customs bottle necks for international shipments especially during busy or peak times like holidays, accuracy of the paperwork provided by the seller with the shipment, and various countries have certain rules regarding packaging that your seller must take into account if one of those countries happens to be yours. Each seller, and sometimes even each item within the same shop, could have different shipping times for any number of reasons. It's best to READ THE SHIPPING DETAILS in the listing and if you are still not sure, contact the seller BEFORE ORDERING.
