I bought some N95 reusable children's masks from a reputable seller (5 digit feedback, 99.9% positive, all the "eBay verified/premium seller" crap)... 4 for $80. They ended up being BLATANTLY fake, basically 1mm craft foam cut out in the shape of a mask. I sent in macro photos and a full description demanding a refund, they said "nope, you opened them, they're used now".
eBay sided with the seller.
I've been on eBay since it first came to my country, I've bought/sold many hundreds of items, but eBay has noticeably become an utter mess in the last couple years, and their support is non-existent. I'll never use eBay again, for anything.
... And eBay/Paypal won their era's fight because they offered the better experience compared to the others, they were considered the safe and reliable one.
Early web shopping really was wild. And not the good kind.
And then came Amazon an roller-steam them all. And in my opinion it's because of their super buyer-friendly, stress free experience.
Every time you would buy a book from them, and you were happy that they gave you the best possible price, they didn't give you hard time when the book was lost in the mail or you wanted to return it because the sent you the wrong book, or whatever, your trust in them would increase.
Once you consumers trust you with buying A, selling them B, is just a matter of making it available through your store.
I see a lot of online stores, operating the old way; with hidden discounts, dedicated seller-teams trying to sell stuff to you, pushing back when you want to return an item, etc. and can't help thinking how they are ever alive.
I recently bought a relatively expensive item ($3k) that was being advertised as "New - Open box" one month old item.
What I received was a 5 year old used item. Trying to return it was the most stressful online shopping experience I have ever had.
One you open a return request, eBay gives the seller 5 working days to reply to your request. Seller took advantage of all 5.
When I finally got a return label, the seller left the item waiting for pick up for 3 days, until finally picking it up.
Once picked up, eBay gives seller another 5 working days to issue a refund.
In the mean time there is no way to ask help from eBay. All they do is just close the case asking you to wait.
So for a total of 3-4 weeks I have my money sitting in seller's PayPal account.
At least with Amazon, retail* support is usually pretty good.
