Anything with a multiplier can be stored later on. I would first get the beach hideaways that you don't have. When fully upgraded, it will give you another 60%. I don't like the MBs so I just buy decorations with multipliers as they come available or others in the store that I don't have. It takes longer to raise your multiplier but it prevents having lots of the same thing. KEM farming is the best way to be able to continue to get money and get donuts. I resisted for a long time, because I thought it would be tedious. Now it is just part of my routine like putting people on tasks. I am not diligent on checking every 4 hours but I still at least 4 times a day.
