Delivery Policy
Thank you for shopping with us! Below is our delivery policy to ensure clarity and transparency regarding your order.
Amazon Shipping – What to Expect
We use Amazon Shipping for our parcel deliveries. While this may seem confusing, rest assured that your purchase is not from Amazon—it is from our eBay store. Amazon Shipping is simply the courier service we use, chosen for its reliability and efficiency.
Having used various couriers in the past, we found that missed deliveries and unclear instructions often stem from small communication gaps. To improve this, Amazon Shipping delivery drivers can now text recipients directly during delivery when needed.
- Messages are sent through a secure channel, so drivers never see your actual phone number.
- They may call to clarify directions, confirm details, or prevent missed deliveries.
- This direct messaging helps ensure your package arrives on time and at the right place.
Ensure Your Contact Number Is Correct
To take full advantage of this service, it’s important to include your mobile number when placing your order. If you’ve already provided one, please double-check that it is correct.
Once you receive your Amazon tracking number, you can monitor your delivery and ensure everything is on track.
