I just started selling some items on eBay again, and you can tell from the sellers side they do the same things. The last 30 days of 2018 you could list items for free. Now that I've been listing items for about a month, they sent a coupon for 50% listing fees.
We should keep track of their trends. Does a site like CamelCamelCamel exist for eBay?....google search, yes! http://www.checkaflip.com/
how about one for eBay Coupons....google search No.
