I am in Canada - I have bought the Quaker chocolate chip granola bars too that are peanut/nut-free, but the Costco Kirkland chocolate chip granola bars are less expensive and I thin they taste better than Quaker too.
Costco also sells chocolate dipped granola bars that are peanut/nut-free (Kirkland brand) - see photo below showing peanut/nut-free chocolate dipped granola bars from Costco (peanut-free symbol on the boxes).
