Today I learned that you can partially fill community center bundles. By that, I mean bundles that want more than 1 of the same item can be filled partially with that 1 item. Furthermore, this lets you get around the need to submit multiple items of the same quality. For example, with the Fodder Bundle, you need 3 apples. If you have 2 silver quality apples and 1 gold quality apple, you can submit the silver quality apples into the bundle, and then you can add the remaining gold quality apple to complete that part of the bundle. God I wish I knew about this sooner.
