This is mainly from a seller's perspective but I think it will be bad for buyers too - put up costs.
eBay are bringing in so called "Simple Delivery" for private sellers on the 15th even if you've opted out so far. Note that Evri and Royal mail are both ticked unless you change it.
I don't understand all the details yet but it looks like the costs will go up for letter, large letter and small parcel. Eg. with RM 87p-£1.55 now will be £2.73. and 3.35 online now (3.90 in post office) changes to 4.27 for 1-2kg.
The buyer protection fee already increased the price to buyers and makes offers confusing to the seller. Now more hikes and potential for errors (postage eBay will guess and add to existing listings). This seems like both buyers and private sellers will lose out. Thoughts?
