Nope, far too complicated for me.
I thought that it was going to be a simple task to re-list a few of my eBay listings this evening but I was "greeted" by the sight of eBay having messed with all the postal charges for my items up for re-listing and undercharging postage on every single one.
I've never even heard of "eBay Simple Delivery" before this evening and after figuring out how to opt out, I had to opt out for every re-listing.
It is suggested online that the plan is to make "Simple Delivery" compulsory for private sellers but currently one can opt out.
I can't understand why "Simple Delivery" undercharged postage on every item I had for re-listing. Do eBay expect sellers to send their wares just in paper envelopes with no protective packaging which obviously has weight?
