Call the Chanel 1-800 #. They'll connect you to a store & have it shipped to you. These shouldn't be difficult to find as they are the continuous line. The large is almost always in stock. The jumbo is a little harder but just give them your name & they'll call you when a new shipment comes in. I'm in California & I know for certain these are available in all the Chanel stores here (even in Bloomingdales, Saks, NM, & Nordstroms).
I have a store there. There are many sellers on Malleries. The are all great, they take authenticity very seriously. Chanel Touch who is a member here has a store also. She specializes in Jumbo Vintage.
