For smartphone bargain hunters, the Google Pixel 4a has proven to be worth the wait. Unfortunately, it also proves that Google's $349 phone is very tricky to order.

The Pixel 4a won't hit store shelves until August 20, but you can pre-order it now. However, demand has already outstripped supply at one popular retailer, and Amazon was showing it as out of stock when we checked on Friday afternoon.

If you struck out on Amazon, don't fret; there are other places to pre-order the Pixel 4a.

The reason the Pixel 4a is an early hit is simple. The $349 price tag is hard to beat, especially when you get a phone that can match many of the camera features on the more expensive Pixel 4. We're also fans of the phone's bright display, attractive design, and generous built-in storage.

If you're interested in getting one, here's where you can pre-order the Pixel 4a right now.

There is only one model of the Pixel 4a: it comes with 6GB of RAM, 128GB of storage, and is only available in one color, black. in addition to Amazon, it is also available at Google's online store and Best Buy. Verizon, US Cellular, and Google Fi are among the carriers offering the Pixel 4a, but as of this writing, it is only available on US Cellular and Google Fi.
