I'm gonna cut straight to the concept:
The idea will work for any physical or eshop.
You charge an extra 10%.
Why would anyone pay extra?
Well, this extra 10% when spread over 10 customers equates to 1 unit. Which is given away at random to one of the people that bought the item.
Take the example of an item that costs the consumer €50. you charge €55. Now after 11 people buy that item you reimburse one of the people at random.
This is all upfront and transparent.
f course, you could reimburse them with a credit note, so they have to spend it in your store. However, unless you are amazon, I think this will limit your growth.
I envision this working on a shop like Amazon, a buyer can opt to pay a % more and be in with the chance of winning the item for free. The bigger the % they pay, the higher the chance of winning. Of course, they also have the option to pay the normal price and not be in with a chance of winning it for free.
The concept plays on people's psychology and cognitive bias on a number of levels.
Also, the reason for doing this is to capture more customers, not to make more money from each customer. It is a way of driving growth.
I love combining concepts and sharing ideas freely. This one hit me out of the blue while in a minor extasis state. Hopefully some of you guys can use the concept to your advantage.
Own your day,
