I agree, if you see the item has been dispatched and it hasn't been delivered yet, just be patient. The postage delays have been well documented. Just this week, I had a tracked 48 small parcel arrive after ten days and didn't chase the seller about it. Tracking showed it as accepted at the parcel shop the day after I ordered, so ultimately the delivery time was out of their control. If an item doesn't arrive, the buyer will absolutely be refunded, so that isn't a worry. I have even opened item not received cases after 21 days (I think you have up to 30 after dispatch ? to do so, if needed).
If I start discussing the estimated delivery dates, it will turn into a rant, lol. They can be unrealistic and create false expectations. I have a three day dispatch time, and after a weekend there are often cases where the last estimated arrival date, is actually the day before I need to actually send it out, if that makes sense, lol. I even had a sale just before midnight recently, yet the estimated earliest possible date of delivery was actually the next day !!!!!
