You're clearly a busy man James, but do you think you could spare the time to tell us a little more about your database? Like, what tables you store the purchase information in. It makes it a whole lot easier to answer your question.

If you had the simplest possible arrangement, you could do this..

SELECT customerID,COUNT(*),SUM(price)
FROM   purchases
GROUP BY customerID

You probably have a more complex arrangement, splitting the price off into a separate "product" table, but I'll leave you to figure out how to adapt the above to your circumstances (whatever they may be)
