Grande Parcel Delivery Box Black

Have had one of these for a few years now. Works well [although some delivery drivers don't seem to understand how to use it, even though we have attached a laminated copy of instructions]. However, the lid has become badly corroded over time, even though bin is situated under an overhang and partially protected from the rain. Also the sticker inside which could be scanned for proof of delivery quickly deteriorated and became unreadable. [Unfortunately as Amazon persist in using boxes much bigger than needed some are too wide to fit in the parcel box]
