Terms & Returns
Effective date: October 16, 2026
These terms apply when you use diddams.com or place an order with Diddams Party & Toy Store ("Diddams," "we"). By using our website or placing an order, you agree to them. Our Privacy Policy explains how we handle your information.
Orders
Placing an order is an offer to buy. Your order is accepted when we confirm it by email. We may cancel or limit an order, for example if an item is out of stock or a price is listed in error. If we cancel after you've paid, we'll refund you in full.
Prices and product details
Prices are in US dollars and may change without notice. Prices online and in store may differ. We try to show products accurately, but colors in photos can vary by screen, and balloon colors and shapes may vary slightly by supplier. If we find a pricing error, we'll contact you before filling the order.
In-store pickup
Website orders are picked up at the Diddams store you choose. We'll email you when your order is ready. Please bring your order confirmation and a photo ID that matches the name on the order.
We hold orders for 7 days after the ready-for-pickup email. Orders not picked up by then may be cancelled and refunded, minus any custom items that were already made.
Balloon orders are ready at the pickup time you choose. Please pick them up on time: helium balloons start to lose float from the moment they're filled.
Party bundles
Party bundles are priced as a set. If an item in a bundle is out of stock, we'll contact you to swap it for a similar item or refund that item's share of the bundle price.
Returns and refunds
Regular merchandise. Unopened, unused items can be returned within 30 days with a receipt or order confirmation. Bring returns to any of our three stores. Refunds go back to your original payment method.
Custom balloons and bouquets. Balloon bouquets, garlands, arches and other custom balloon orders are made for you, so they can't be returned or refunded once they're made. You can change or cancel a balloon order up to 24 hours before your pickup time for a full refund.
Final sale items. Opened costumes, makeup, wigs, candy, helium tanks and items marked final sale can't be returned, except when they arrive damaged or defective.
Damaged or wrong items. If something is damaged, defective or not what you ordered, let us know within 7 days and we'll replace or refund it. For balloons, please tell us at pickup so we can fix it on the spot.
Bundles. A party bundle can be returned as a whole set. If you return part of a bundle, we'll refund each returned item at its regular single-item price, up to what you paid for the bundle.
Balloon safety
WARNING: CHOKING HAZARD. Children under 8 yrs. can choke or suffocate on uninflated or broken balloons. Adult supervision required. Keep uninflated balloons from children. Discard broken balloons at once.
Some balloons contain latex. Foil balloons can conduct electricity, so keep them away from power lines, and never release balloons outdoors. How long balloons float depends on size, temperature and handling; times on our product pages are estimates, not guarantees.
Our responsibility
We aren't responsible for delays or problems caused by events outside our control, such as weather, supplier shortages or power outages. To the extent the law allows, our responsibility for any order is limited to the amount you paid for it.
Website content
The text, photos and designs on diddams.com belong to Diddams or our suppliers. Please don't copy them for commercial use without our permission.
Changes to these terms
We may update these terms from time to time. Changes apply to orders placed after the new effective date. These terms are governed by California law.
