We hardly use foil or saran because we put all our foodstuffs in plastic containers, mostly Sterilite ( made in MA but it is really affordable in Maine at Reny's, go figure) The 4 ou. size are usually little lidded clear bowls or rectangles. We have found inexpensive Glad brand before, but cannot find them now in our area. The Rubbermaid ones we found last week are TOO expensive (c.$2 @!!) Anyone seen 4 ounce ones in the Boston area up to So. N.H.? (not So. o Boston) ? We have been looking all over, but are now asking the eagle eyed hound community!TIA!
