I searched this MB and found a recipe for Rum Punch but I have a question about one of the ingredients. It calls for 1/2 bottle of bitters? I have no clue what bitters are or where to begin to look for them!
You will find bitters in most supermarkets that have a "drink mixers" section....by the wine a lot of times...Angostura bitters is the most common brand...if you have a section that sells margarita salt,grenadine, rose's lime juice, cocktail olives,drink umbrellas, etc...you will see the bitters in a bottle similar to a worchestershire sauce bottle.
