My package for skechers men go 600 running shoes was delivered without any price tags on the box but all other details on it.
I placed a return request due to size issue and my return request was declined as it didn't have price tags where those price tags were not even there initially.
I got in touch with customer support and they have declined the return request as they are saying they have sent the box with price tag which was not even there.
