I went to Sam's Club (no comments please) this afternoon for canned air, and was told they don't carry it anymore. So I picked up a bag of 3000 tootsie rolls (no comments please) and at the check out counter was a package of Zeiss Lens Cleaning Cloths. They are pre-moistened and have 180 little packs inside. The cost was only $8.86. Just thought some of you might be interested.
