All this talk about foil made me remember this one deal I passed up. That was on March 17, a little over 2 months ago. The roll that was $3.97 at Walmart is now $4.98 there! :O
But anyhow, Amazon put the 130 sq. ft. heavy duty rolls of Reynold's Wrap on sale for $5 and change each a couple weeks ago so I ordered some of that.
They also had the regular (not heavy duty) 200 sq. ft. rolls for something crazy, I think it was $4.54 a roll, but I didn't order that one because I'm still working on a mega sized roll I got a few years ago, I think from Sam's.
The heavy duty kind can be washed and reused a lot more times also.
