I puncture small holes in the bottom of the cooler, then glue the top to the bottom, so there’s always a small amount of moisture for whatever’s in the cooler. I’ve done this for
3 years. The coolers do a good job.
If they are totally cheap, which they are, and you've already gotten three years use out of them, that's worth it. There are two dollars stores on my “shopping street”, the most unique street in the world for shopping. That one street has everything except your medical doctor and hospital which is 5-6 minutes away from that street.
Rightly, how do you feel about our shopping street from HEB down to Lowes? You must be as aware as I am, of everything and anything being available to the right and left on that street.
