Had enough of "Simple Delivery"? Me too
Why isn't it actually simple? Here's how it COULD work: eBay holds the money for the item until you have selected the parcel size or have scanned in the item, now it knows how big the parcel is and takes out the correct sum of money! Yay, no issues!
Here's how it currently DOESN'T work: eBay estimates the parcel size and changes it after sale anyway (At first it was when buyer bought multiple items, which still COULD have fit in the same parcel size!) and you CAN'T downgrade the postage option, leaving you out of pocket.
Multiple times in the past 2 months I've sent items outside of the service now, ignoring the label because it's WRONG. I'm pretty sure they've kept my postage money, too, so I'm going to have to message them for refunds now... I guess I'll end all my listings and come back if they ever fix this.
