The address might be incorrect: Your product might never get delivered if your address isn’t correct. Incomplete address: If your apartment or street number is missing, or even the floor number then your delivery can’t possibly be met. International custom procedures: Depending on the country, there will be due processes that must be met before products can cross the border. If there is any complication in this step, the arrival of the product will be delayed. Severe weather conditions: Under severe weather conditions like a storm or heavy snowfall, product delivery will be delayed until more favorable weather conditions arise. Increased online ordering: With the influx of many buyers, processing will be delayed due to the surge in customers. This will be easily resolved but might cause a slight delay in delivery.
