"I had to walk to school 40 miles in the snow... barefoot" was good in it's day. But imagine the sheer terror on your kid's face when you drop "When I was born there was no internet".
When I was younger, my mom would give me $2 to go to the grocery store and I would bring a dozen eggs, bag of candy, gallon of milk, a box of tea and potato chips. I can't now though, there are surveillance cameras now.
So...if Wal Mart can sell a TV for $100 the day after Thanksgiving when they're paying 500 employees to work, why can't they sell it for $90 today when there's only 8 employees in the whole store??
