I keep my costs to the bare minimum. I started it because I wanted decals no one else was making. I cannot justify feee shipping.
In the UK I eat the cost as it is about £1 to ship UK wide. Posting to the US is now around £7. I need to send tracked thanks to the selling platform.
It honestly pains me to have to charge shipping - but I could’t do it any other way. I can only imagine the costs that are associated with this for bigger outfits. Heck. Even Amazon has a logistics company now (but I suppose that’s where the Prime premium comes in!)
