Online search. Only problem part my fault. placed order for 6" pans. THEN thought of using 24/7 pro line and asking about 8" because couldn't find them on same site to order. There was mix up when pro told me they had them and would cancel for order and combine them for the 4 pans so I would pay only one shipping charge. It didn't get done. I had to call them back. Then they had to call me back. But overall would use them again. Very courteous pros. Was shipped promptly. Parts were available and were the right fit even through part #s had changed several times. Only thing I would want them to change would be to make sure both 6" & 8" were listed on site then I could have ordered right the first time. My reasoning, if they have to order one size, more than likely need other size too. Thanks.
