Lesson #2 - When driving to E-Mart during the week, pull into the parking garage - just when you think you need to pull a ticket the bar goes up and lets you in. No tickets needed. They just took a photo of your license plate stamped with the time you arrived! (How awesome is that?) No fear of losing that stinkin' parking ticket!
Lesson #3 - Shopping carts, sure their shopping carts are just like shopping carts you find in the states, EXCEPT they are all chained together! How do you get one? Put 100 won in the slot and unlock the cart. Take your cart inside and shop away.
Lesson #10 - Just like Super Target, you will always spend too much money at E-Mart.
