I had the same issue but after I deleted the mailbox bought a different one and put it closer on the lot instead of the furthest tile it worked.
I was having the same issue, but my mailbox was slightly hanging over the edge of my lot and that seems to fix it.
I was having this issue too. Replacing the mailbox worked for me
I figured out my issue. Mine live in an apartment. I had to actually have my sim in the lobby near the mailbox first and then it worked
Ship to Buyer no longer breaks when the Sim replaces the Mailbox on their home lot. Trendi sales can now be completed.
Fixed in Patch 1.99.264/1.78
