duplicating and incrementing records vfp

Hi:
Trying to wean my staff off excel....
I have 100 customers and 10 products. Each customer has a different price for each product.
Currently I have 100 excel sheets
I have created a customer table with 100 records and a product table with 10 records.
So I believe I need now to create a joining table  (called say "price") comprising 3 columns - customer , product, and price for that product.
Is there any fast and easy way of looping through each customer in the customer table, appending to the price table 10 records for each customer,pulling each product from the product table? So I end up with (100*10) 1000 records? One record for every product for every customer?
 I can make the product code sequential 1-10 if easier!

i don't know foxpro, but the way i would do it in MSSQL would be as follows:
declare cCustomers scroll cursor for select customerID from customers
declare @i int = 0
open cCustomers
fetch next from cCustomers into @i
while @@fetch_status = 0
BEGIN
	insert into customerProduct(customerID, productID, price) values(@i, product1ID, product1Price)
	insert into customerProduct(customerID, productID, price) values(@i, product2ID, product2Price)
	insert into customerProduct(customerID, productID, price) values(@i, product3ID, product3Price)
	insert into customerProduct(customerID, productID, price) values(@i, product4ID, product4Price)
	insert into customerProduct(customerID, productID, price) values(@i, product5ID, product5Price)
	insert into customerProduct(customerID, productID, price) values(@i, product6ID, product6Price)
	insert into customerProduct(customerID, productID, price) values(@i, product7ID, product7Price)
	insert into customerProduct(customerID, productID, price) values(@i, product8ID, product8Price)
	insert into customerProduct(customerID, productID, price) values(@i, product9ID, product9Price)
	insert into customerProduct(customerID, productID, price) values(@i, product10ID, product10Price)
         fetch next from cCustomers into @i
END
deallocate cCustomers

Customer (id, customer, address, phone, ...)
Product (id, product, defaultprice, ..., order)
CustomerProductPrice (customer, product, price)

SELECT Customer.id As customer, Product.id As product, defaultprice as price;
 FROM Customer, Product;
 ORDER BY Product.order;
 INTO CURSOR temp
SELECT CustomerProductPrice
APPEND FROM DBF('temp')
