Nothing I had not bought before, the red flag 'customer service' quoted was my listings stated 10/15 day handling time and instead it was delivered in less then 4 days(under promised and over delivered with 3 day shipping) Shipped basically the same day and they thought that was worthy of locking me down as being suspicious instead of them considering maybe I was treating customers the way i would want to be treated .
If ebay starts charging the buyers, the buyers will start to look elsewhere to find what they want. I don't sell on ebay, but I do buy odds and ends. I got a burr under my saddle and decided I wanted to get a set of all of the silver FDR Coins. For the most part, the prices were reasonable. I found the FDR Dimes from about $4 to $8. A few of them I had to go up to $12. Only few charged S&H. I would look elsewhere for a coin that didn't charge S&H. Usually I add the price with S&H to determine the total cost. If the total cost was above my preset budget. I look elsewhere. There are always other vendors that won't try to scalp you with S&H or some other stupid cost. Anyway, as a strictly buy ebay customer, ebay prices are usually very reasonable.
Part of that too is eBay basically forces you do to free shipping or they bury and sometimes just hide your listing completely
After a year of pandemic related shut-downs and no in-person coin shows, many hobbyists are now inundating shows as they open back up. Between unreliable USPS service and all the other headaches associated with "remote" coin collecting including ever increasing fees heaped on sellers, there is likely a renaissance coming for those looking to bypass all the greed and nonsense associated with internet based organizations that aren't even part of the coin collecting community. eBay can continue to post full-page self-congratulatory ads in all the hobby publications, it doesn't change the fact that most in the hobby now view them as little more than a parasitic barnacle trying to suck the life out of the hobby. Ditto PayPal. We all got by fine without them before they appeared on the scene, and their rapacious fees are begging all of us to show them who has the upper hand in the deal: Hint, it isn't PayPal or eBay at this point.
Paypal was not founded by eBay. In fact in the first year of Paypal's existence eBay advised people to avoid it because it was most likely a scam. Then when they saw that people were flocking to Paypal and they were making a lot of money, eBay bought Paypal. (When Paypal started up they also PAID people $5 to join, and made the promise that Paypal would be free forever because they made their money off the three day "float" period.)
