Prime Exclusive Discounts

Given that the deal price needs to be the lowest within the last 30 days, if we set a PED at $10, is it possible to offer the same $10 price for the Best Deal?

Or would the Best Deal price need to be at least 20% lower than the $10 PED price?

I think that the Best Deal would need to be lower than the PED price, typically at least 5-20% lower. Try and you will see.
