Crest has the widest range of whitening strips products and, therefore, the widest range of prices. In late 2009, Crest Classic, Premium, Pro Effects and Advanced Seal cost $24.99, $34.99, $39.99 and $44.99, respectively. Listerine's Whitening Quick Dissolving Strips cost $14.99 and Rembrandt's Whitening Strips cost $23.99.
