If you don't want Simple Delivery on your listings please complain directly to eBay
I just did.
If you like it that's fine I just don't understand why, after April 15th it's going to be compulsory for personal sellers on items over £10.
Everyone that wants to choose their own postage please complain. They won't listen if we don't.
I've been an eBay seller for 21 years so much for supporting loyal sellers.
