You can buy helium balloons either already filled or as empty balloons plus a helium tank; where you go depends on price, convenience, and whether you need bulk.

Main places to buy helium balloons

1. Party and balloon stores (most convenient)

  • National chains like Party City sell helium balloons of all types (latex, foil, numbers, letters) and will usually fill them for you in-store for a per‑balloon fee or as part of a bouquet.
  • Many independent balloon boutiques and decor companies offer custom bouquets, arches, and delivery for events (birthdays, weddings, corporate functions), often with same‑day or next‑day service in larger cities.
  • These shops often let you:
    • Order online and schedule pickup or delivery
    • Choose themes (birthday, baby shower, graduation, etc.)
    • Add extras like weights, ribbons, or small gifts

Best for: If you want a ready‑to‑go bouquet or event decor with minimal effort.

2. Big box, craft, and discount stores

  • Craft stores and big‑box retailers (e.g., Michaels, Walmart, some supermarkets) typically sell helium‑grade latex and foil balloons, and many locations also offer in‑store helium filling for a fee per balloon.
  • Discount chains (like dollar stores) frequently sell pre‑filled helium balloons or will fill balloons you buy from them, which can be one of the cheapest options if you don’t need a big, customized setup.
  • Grocery stores often have a floral section that fills balloons and sells ready‑made helium bouquets. Forum discussions commonly mention supermarket floral departments as an easy walk‑in option.

Best for: Small parties, last‑minute balloons, and budget‑friendly options.

3. Online balloon retailers (ship to you)

  • Specialized online balloon shops ship helium‑quality balloons (latex and foil) and accessories nationwide; some focus on wholesale or bulk pricing for decorators, businesses, or big events.
  • These stores often have:
    • Large selections by color, size, and theme
    • Balloon garland and arch kits
    • Options for wholesale discounts and event‑planner quantities

Best for: Bulk orders, specific colors/themes, or professional decorators who already have helium.

4. Party supply wholesalers and pro suppliers

  • Wholesale party‑supply platforms and balloon‑specific wholesalers sell helium‑rated balloons in large quantities for businesses, event planners, and venues.
  • They emphasize checking that balloons are specifically labeled as helium‑rated (thicker and designed to hold helium longer) and often carry specialty shapes, branded characters, and large outdoor advertising balloons.

Best for: Businesses, people hosting frequent large events, or anyone who needs a lot of balloons at the lowest per‑unit cost.

5. Buying a helium tank and filling at home

  • Many party and event‑supply retailers sell or rent helium tanks and “helium tank + balloons” kits so you can fill balloons yourself at home.
  • Typical steps include securely fastening the tank upright, attaching the nozzle, carefully inflating balloons to the recommended size (not over‑inflating), tying them tightly, and closing the valve when you’re done.
  • DIY helium can be cost‑effective if:
    • You have many balloons to fill
    • You need to inflate them right before the event
    • You want flexibility in timing instead of relying on store hours

Best for: Larger parties at home where you want everything ready on‑site and on your schedule.

A few quick tips

  • Always check that balloons are labeled as helium‑grade so they actually float and last longer.
  • If you order online, factor in delivery timing so the balloons or tank arrive at least a day or two before your event.
  • For cheap, last‑minute helium balloons, many people report success at dollar stores or supermarket floral sections rather than only at big party chains.
