In the Top 3 daily AVG Sales column I'm looking to write a formula that calculates the average top 3 sales for each day per Retailer and Product Type. So, if date is 01/01/2021 and Retailer is Retailer 1 and ProductType is Mobile, find the top 3 sales and average them => (2200+2700+1400)/3 = 2100
Appreciate any help with this.

You can try-
=AVERAGE(INDEX(SORT(FILTER($B$3:$B$42,($A$3:$A$42=A3)*($C$3:$C$42=C3)*($E$3:$E$42=E3)),,-1),{1,2,3}))

=AVERAGE(LARGE(IF(($A$2:$A$42=A2)*($C$2:$C$42=C2)*($E$2:$E$42=E2),$B$2:$B$42,""),{1,2,3}))
Press CTRL + SHIFT + ENTER to evaluate the formula as it is an array formula.
