Simply Delivery should be renamed Shockingly Inept Delivery.  There is no way eBay can possibly know:

- what I am selling (based purely on the listings or title of the listed goods)

- how I intend to package it up to protect it from damage

- the size of packaging I'll use (or the amount)

- the weight of the complete package

- and/or how much Royal Mail (or any other delivery company) will charge for it.

Forcing me to charge only a set figure based on assumptions, means I - as the Seller - lose out on money, as inevitably postal charges cost way more than eBay let me charge for sending within the UK.  My loss can be a few pennies, or it can be a few quid.  Moreso, if I want to send it tracked and insured.  I now have to add notes to my sales, that I will NOT send anything by Evri/Hermes, and buyers who ask me to do so, will find their request ignored.  (The fact that Evri are incompetent and lose every parcel in their delivery system, thanks to their many helpful 5-finger-discount staff, is why I refuse to use them.)

It's a state of affairs that eBay thinks it can tell Sellers what to do, how to do it, and take a loss all at the same time.  I don't think I can understand them any more!

Such a decision is absolutely backwards, and has really put me off selling stuff via eBay.   They seem to want complete control  over every aspect of every sale.  I wonder how long it'll be before they start demanding video evidence of our goods or asking Sellers to install cameras in our homes, so they can see what we are selling?!

eBay are absolute animals!  Let me decide what my postal charges need to be, based on what I am posting and how I am posting it!
