for a WC? i'd let the water age for a few days or in the mean while order some online. unless your tank is in immediate need of a WC, your fish can wait a few days.. no biggie. you can cut down on the feedings if it makes you feel better lol good to see you're one of those religious WC guys, but one time won't hurt. your stock isn't too big, given you have 60 gallons of water as well.. it'd be weeks or months before your nitrate gets extremely high to kill your fish.
small town you live in? really odd they can't get water conditioners if they are still shipping in other products to the store.
