They have an expiration date of 4-5 years, so not really an issue. I just think it's a waste of my time to go to the store to get a 10-20 pack and also a waste of space and a waste of packaging.
Small annoyance overall I know, but it's one of my gripes about over the counter medicine here.
Edit: more annoying is that more hardcore cold medicine is not sold over the counter here at all. Anything with pseudoephedrine is prescription only. Also the sort of actually effective decongestants and antihistimes are all prescription only if they're even legal at all here.
But what's funny is despite that, I can literally walk into the grocery store and buy codeine cough syrup right off the shelf without asking anybody or showing ID. It seems ridiculous to me.
