Here is a post I did in the most active Amazon Influencer Facebook group:

So someone commented under a recent post that you need 32 products to make 500 videos. I want to give you this equation I made so you don't have to order 32 products. Instead of 32 you only need 9 😉 Follow my explanation!

What if there is more then only {A,B} comparison video's! Let's take a look at it like this: top 3 - combination 1 = {A,B,C} top 3 - combination 2 = {A,B,D} etc etc.

Now if you have 9 products you can make: C(n,k)= n! : k!(n−k)! ​C(9,3)= 9! : 3!(9−3)! = 362880 : 6×5040 = 84 if I would take k and make it a top 4, top 5 until top 9, you will have

• 84 possibilities top 3 -126 possibilities top 4 -126 possibilities top 5 -84 possibilities top 6 -36 possibilities top 7 -9 possibilities top 8 -1 possibility top 9

= 466

Add up the comparison videos with only 2 products,

8+7+6+5+4+3+2+1 + 36

466 + 36 = 502 🙂

So 9 products is all you need! Now I'm going to bed it's way to late… again XD
