I found a 2-pack of Clear Care cleaning and disinfecting solution with lens case on Amazon. This 2-pack is usually priced at $21.99, but it's on sale right now for $18.39. To get an even lower price, clip the coupon for 25% off. Then check out with Subscribe & Save for an extra 5% or 15% off. You could pay as little as $11.03 for two bottles of contact solution and a lens case.
