I bought a box of aluminum foil sheets that are leafed -- like facial tissues -- for a better price per square foot than the rolled type at a restaurant supply place. But it's so often not the length I need that I end up using the rolls. I think buying the national brand heavy duty is worth the money for the quality difference from the store brand. And I pinch pennies 'til Mr. Lincoln hollers.
I got the big roll plastic wrap in a box once upon a time when I had more counter space. I really loved the little slider/cutter on the box.
No matter how simple it seems, it's complicated.
