The estimated delivery date is when your order should arrive. Generally, the estimated delivery date is based on a combination of the processing time for the items you ordered (how long it takes the seller to create and prepare them for dispatch).
Each seller on Kaufpedia adds the estimated date.
For example: If the processing time for an item you purchased is 3-5 days, your estimated delivery date is 3-5 business days from today.
If you’re a seller, setting up estimated delivery dates can help both to drive sales to your shop, and prevent unnecessary buyer confusion.
