I'd be mad to buy a wireless security camera that was missing its proprietary reciever and I couldn't return or hook up any other way.
Shameful, just shameful. I accidentally walked out of a Kmart with a 9 volt battery in '89. I needed both hands to look at something else. I found it when I got home, turned around and drove 45 minutes (an hour and a half round trip) back to the store to pay for it.... in a snow storm. The aggravation and nasty driving conditions were nothing compared to the lack of sleep I would have if I didn't make it right. The clerk at the store thought I was nuts. Maybe so, but I sleep well.
I looked at him and said "It's pronounced 'Thank you'" and left.Def
