Why are there express lanes for people who buy a small amount of stuff?
We should have express lanes for people who buy a ton of stuff.
How about this: If you fill your cart over the top, you get to use the SuperLane! The SuperLane will give you two cashiers, two baggers, and a fresh cup of coffee waiting to get you on your way.
The lesson: Find ways to reward the folks spending $200 instead of $20.
