I never heard of having to take ones old (spent) light bulbs back (i.e. to a currency exchange). If you paid your electric bill at a currency exchange so authorized by commonwealth Edison you were allowed a couple free regular wattage bulbs each month, all you had to do was ask for them on payment. But bigger wattage bulbs, if stocked, would required a small extra charge to get from an exchange. In the 1980's I'd do this from time to time at a couple Chicago currency exchanges (they'd also not charge you any bill payment fee and you were in the clear up through the due date, which practice unfortunately's discontinued). For reasons never explained one exchange got me in a little trouble back then, in that I paid an electric bill there on time but the Edison people said they never got it and marked me overdue with the next billing. Luckily for me I kept the stamped stub and was able to read all the pertinent paid information over the phone to them for account rectification (it maybe my perception but the Edison operator seemed a little skeptical, and it is unusual).
