15-Pack Reusable Nylon Produce Bags | $10 | Amazon | Clip the 5% coupon
Turns out, you can get reusable sacks for those too, and this set of 15 is down to just $10 today after you clip the 5% coupon (the $11 list price is the best in a few months to begin with). They’re made from nylon, but transparent enough that your checkout attendant won’t have to open them to see what’s inside. And if you don’t need all 15 for shopping, they can be used for holding just about anything. So go ahead, do Mother Earth a solid.
