I wish I could figure out how to give people precise instructions without sounding like I think they're an idiot. Like. Please buy me some pseudoephedrine-based decongestant. Do not under any circumstances buy me phenylephrine-based decongestant. Specifically pseudoephedrine based, please. Come back with nothing otherwise.

Then they come back with phenylephedrine-based decongestant "because that's all they had" and I add it to the pile.
