I've got an ethical dilemma on my hands, and I'm seeking advice. But I think the underlying issue is very relevant to all of us: when a "good" mistake happens to us, is it serendipity or just a mistake that we have an ethical obligation to fix? (Apparently "fix" is a very Southern verb. Just go with it.)
Here's my dilemma:
I take a daily medication. My bargain-basement student insurance (evilly, in my opinion) makes me fill it every month, even though it is available in a 3-month supply, which is significantly cheaper than purchasing one month at a time. I don't know what happened this month, but they gave me the 3-month supply, and I didn't notice until almost 2 weeks after I filled the prescription. I don't have the receipt anymore, but I'm pretty certain I only paid the (higher-per-unit) one-month price.
Should I attempt to return the two extra months' supply to the pharmacy? (I'm not even sure that they can take back "used" medication since it may have been tampered with.) Or, knowing that the next two months are going to be tight financially, has HaShem sent me a little goodwill?
UPDATE: Bright minds have confirmed that I cannot return the medication, but that I may be able to pay the difference. However, because of the insurance rules, I'm not sure that I would be allowed to. I might be liable for the non-insured price :/
PS: The irony of a big ethical dilemma the day before my professional responsibility exam was not lost on me.
