I always use reusable bags personally, but when I side hustle for Instacart, plastic really is superior. Walking up snowy driveways with paper bags opens you up to all sorts of possible accidents and spills... Not to mention how easily paper can tear as you move bags in and out of your trunk. And the fact that each arm can really only hold one paper bag... With plastic, many folks can carry 3-4 bags per arm/hand. It's not a perfect product, but it's a step in the right direction. Most people do reuse plastic bags for kitchen waste, pet waste, and a bag to perhaps carry food, or keep clothes clean when you donate clothes in donation bins, or a place to hold tools/wires/cords/knick knacks, etc. Plastic is quite versatile and most people do save and reuse. Hoping that someday they can invent a "better biodegradable" ... But I feel a little less guilty than I used to... And I like how sturdy it is, while providing ease of movement... Thanks!
