For those wanting to DIY saline solution, here's pure, USP sodium chloride tablets (fwiw, USP/pure is the only thing we'd consider using)
Amazon.com: Sodium Chloride 1 Gm 100 Tablets: Health & Personal Care
It took us forEVER to locate USP sodium chloride/NaCl in a "buyable" pre-measured quantity (and from the
reviews, we're not the only ones). We just ordered a bottle...how cool, "1 gram" tablets

These (and the powder) can also be found on eBay. Most of the powders are ACS/Reagent grade - which is MORE pure than USP (but some have added iodine).
Btw, one 1 gram tablet + 110 mls distilled water = .9% solution
Time is short - the list is long. Hopefully some time'll free-up to post/share more soon!
