I have looked at and researched all of their "OTC" products - vitamins, painkillers etc. They are what they say they are. You do need to know a bit of the costing issues in terms of the per dose $. You can buy their small packages - great for travel - and you might save. Costco on the other hand sells huge quantities and generally you will save on per dose. So the questions are price per dose, how much will you need, what is the best before date, do you NEED it etc. Good luck. I have much more info if anyone wants it.
Dollarama has changed. There are many more high quality name brand items at very competative prices. It still has junk and I expect it always will but the new lines have the side benifit of highlighting the difference. Good deals to be had!
