Ugh yup. My regular pharmacy is a pharmaprix (shoppers drug mart), which is one of the biggest chain pharmacies in canada. The cold and flu isle is right in front of the pick up counter, so when I was sick a few months ago one of the pharmacists flagged me down when they noticed me hovering around the cough drop/coldfx/oscillococcinum part of the isle. The amount of proverbial snake oil on the shelves is bad enough that she was apologizing for how confusing it was. Got me set up with OTC pseudoephedrine instead! (There's some combo PSE/acetaminophen meds they sell in front of the counter, but they're mixed in with the sugar pills.)

It's really worth talking to your pharmacist even if you know what you're buying. There's so many more options behind the counter and they're really knowledgable.
