Yes, you can fill your own balloons with helium, and as of 2022, Dollar Tree stores are no longer able to fill balloons purchased elsewhere. If you prefer to fill balloons by filling them yourself, we sell a selection of small and large helium tanks that are perfect for filling at parties or events.
Dollar Tree offers to fill helium balloons free for customers who purchase helium online or in-store at a participating store or station. Dollar Tree can only fill the foil balloons that are sold in-store, and sells a limited amount of pre-filled balloons in-store. Unfortunately, it is not possible to purchase helium from other stores and fill a balloon that is filled with it.
