Cheap, and convenient to find when you need them, almost every gas station sells these.
Vicks cough drops are awesome, I find they work almost if not better than halls for a sore throat

These work really well,they don't have the greatest taste but they soothe your sore throat and ease your cough. I don't find them expensive, great for when you're sick

My throat has alot of problems concerning dryness or inflammation, so this really helps, i love the flavour of it and the fact that it works (i used to hoard these.... i have said too much XD)
