Product inventory is NOT updated in real time. Items can sometimes be listed in the Zipline app that have run out of stock in our partner store. If that happens, your item will be removed from your order and you will not be charged. You may place another order for an alternate product.

Zipline's catalog of products is a subset of items available at our partner stores. Not all products available in store may be available via Zipline delivery for a number of reasons.

The partner store doesn't allow Zipline to sell certain products. Zipline's catalog is governed by what the store allows us to sell on their behalf.

Federal Aviation Administration (FAA) regulations prevent us from flying certain products deemed hazardous material. These can include things which are flammable, caustic, corrosive, or otherwise dangerous to transport. This may include liquid products, oil-based products, certain types of batteries or products containing some types of batteries, certain prescription medications, or any other items that are illegal or prohibited by the FAA's existing regulations.

Inventory information provided by partner stores may temporarily or permanently remove items from the Zipline app. These inventory changes are not controlled by Zipline. If you've seen something in the Zipline app previously and can no longer find it, it may have been removed by the partner store. You may always request access to this product through Zipline and we will send requests for products to our partner stores for consideration.

Temporary out of stock situations may remove items from the Zipline catalog. When partner stores update our inventory data, if products are out of stock in store, the Zipline app will reflect that.

Seasonal items may only be available during certain times of the year in the Zipline app.

Regulations apply to how much weight Zipline can deliver per flight. If items are too heavy to fly, they will not be available for order in the Zipline app,

Dimensional constraints of our aircraft limit Zipline's ability to delivery certain products. If they can't fit inside the compartment of the Delivery Zip, they shouldn"t be available for sale and will need to be marked as unavailable.

You can recommend or request products be made available through our partner stores. Zipline will pass such requests to the partner store, but Zipline cannot guarantee products will be added.
