I know, kind of an offbeat deal for this board, but by Israeli standards it's a great deal!
Everyone here knows how outrageously priced Listerine/Colgate/Oral-B mouthwashes are (I'm talking 4-5x more than US prices).
I use the US Walmart price for a 1.5L bottle of Listerine (usually $5-$5.75) as my baseline when considering if a mouthwash is a good deal here.
So if we buy 3 of these (total 1.5L), it comes to ₪29.70, or $7.80 -- fabulous deal for Israel!
(And on an aside, cheapest mouthwash I've ever seen here has been Life (Superpharm) brand for ₪8.90 -- and only once)
