Ebay does not need to give buyers their own estimated delivery dates, the carriers have their own stated delivery windows for packages. They are from the carrier, they are more accurate. But Ebays estimates are often listed as being earlier/faster than the carriers, to give buyers the illusion they will get their items faster than they actually will, and this leads to more frustrated buyers. Also ebay estimates are not shown as "estimates" but appear to appear more like guaranteed hard delivery dates. Ebay also makes no mention of each sellers handling times.
So please stop doing this and causing unnecessary problems between buyers and sellers. Stop putting your own estimates in and stop presenting estimates as hard/guaranteed delivery dates. Ebays package estimates are causing problems between buyers and sellers by creating false expectations and ignoring the carriers own estimates, plus sellers' individually-set shipping policies.
This causes harm by straining buyer-seller relationships, increases unnecessary INR filings, possibly causing loss of the sale amount to a seller, more work for ebay to return money to a seller, and makes buyers less trusting of the platform, not to mention more unnecessary headaches for sellers. And ebay could just show the more accurate carrier estimates and not be involved in this aspect whatsoever, and it shouldn't be since carriers do this on their own for each of their tracked options.
