Hi is the bulk listing not working? I'm assuming it's not etsy?

Me again 😩 I'm on etsy and trying to get add postage. Where does everyone post to and what are the charges?

Hi can anyone help, not sure where to add the additional £2 and £4 so that it will be added to the sale price of the posters.

I've only got 18 prints but have no clue how to list them in etsy is it worth using the bulk listing. I'm wanting to add 15 new prints a week so I pay for the bulk listing everytime? And when I'm in etsy can I sub categorise my prints? Thank you 😊

Obviously I'm a newbie 😩 I'm uploading my prints today and Im only offering them in the A sizes, I'm using kittl for downloading. So I just want to double check this is the right size A1 W:23.4 x H33. 10 DPI 300 pixels 7020 x 9930px with optimised quality. And can you confirm from this size you can resize to the other A sizes before I have a breakdown 🤣
