The Japantown in San Jose has issues of Corocoro comic at the bookstore in the Mitsuwa supermarket! As of now there are July and September issues, sadly there are no more August issues but the store will have the new issues every month. Also if you wanted to ask for a specific item that isn't at the store you can ask the staff to call another Japanese store and ask if they have the item you are looking for.
