complex

I have three tables, Customers, Sales and Products.

Sales links a CustomerID with a ProductID and has a SalesPrice.

select Products.Category, AVG(SalePrice) from Sales 
inner join Products on Products.ProductID = Sales.ProductID
group by Products.Category

This lets me see the average price for all sales by category. However, I only want to include customers that have more than 3 sales records or more in the DB.

I am not sure the best way, or any way, to go about this. Ideas?
