A blender is easily cleaned. Blueberries, blackberries, cherries and peaches can be bought in every supermarket in any season, I buy them in jars because I'm not a millionaire either. Goji berries are sold dried at those hippie stores, they have flaxseed as well. I make smoothies for three or four days, and put them in small plastic bottles that I take with me to the gym. It doesn't get much easier than that.
