I run an online business and around 2-3% of my orders I get messages from customers saying thier items have not arrived. Most of them do not realise I can track the item and use the GPS to determine the house it was delivered to. I politely suggest they've contacted me by mistake and 99% of these then either miraculously find it or I never hear from them again. There's whole pages on facebook for people to advise them how to get items for free from online companies, what is wrong with people? I wonder now if for every 100 people I come across 2-3 of them are secret thieves! Please if you ever think of doing this, remember there's often a small business behind the website that you're hurting, rant over!
