Even if you have central air conditioning or a window mounted unit, consider getting a portable evaporative cooler. These small units are attractive, energy efficient, and do a good job of cooling. They also often have wireless remote controls, on-off timers, and include air purification (great in case of smoke in the area). Use the cooler instead of your AC and put it near you— just like a fan. Direct cooling is much cheaper than cooling the whole house. And you'll love the extra humidity these units add. You can even move it from room to room. Just put water in the little tank and you'll start cooling right away. They can cost as little as $60 and start saving you money right away.
For a great weed killer, mix 1 gallon vinegar, 2 cups Epsom salt, and 1/4 cup Dawn dishwashing soap (in original blue). Mix and spray in the morning and you’ll never buy toxic products again!
