Getting misdelivered items back to our warehouse and sorted back into stock was a nightmare, and generally we tried not to if at all possible. Whenever a member of the public called us to report they had received a package intended for one of our customers, we would generally ask the caller if they wanted to buy it from us for a large discount. If they declined, we would either let them keep it for free, or if we felt the value of the item justified it we would make an attempt to get it brought back to us. However, between couriers not turning up to collect it on multiple occasions (presumably because there was no real incentive for them to turn up), the homeowner not being at home when the courier arrived, the item being stolen from the homeowner's driveway before the courier getting to it and the courier "losing" the item in transit, the percentage of items that actually came back to us was quite low. In addition, it was then all but impossible to put the item back into stock, since the product line may have come to an end, the package may not be complete, etc. Generally the item would be sold off at a massive discount to staff members. The admin costs through this process would be considerable.
