This works if you live in a dry climate and get some plain cloth bags. I made my cloth bags out of sturdy kitchen towels. Before going to the market, soak the bags in clean water. When foods go into the bag, they will keep cool and fresh until you get home. It's the miracle of evaporative cooling! Be sure to rinse and dry the bags after use.
Instead of buying new hand soap pumps every time I run out of soap I purchase a sturdy-looking foaming hand soap pump and keep a jug of Dr Bronner's Magic Hemp Soap (liquid hemp-based castile soap) around. When the pump gets empty I just rinse it out then fill 1/3 of the way with the Bronner's and the rest of the way with water because it can be diluted quite a bit. It gets hands clean with irritating or drying them out and lasts a long time! The almond kind smells great, too!
Instead of tissues, carry a handkerchief. They don't fall apart in your pocket and you can't blow right through them. Throw it in with your laundry when they get messy and you can use it again and again. You can also use bandannas as a handkerchief, too--which can be fun and colorful.
