Google's new Google Pixel 3a and 3a XL phones have the potential to be more widely adopted by the company, with a competitive price and greater carrier availability. Another point in favor of 3a: everyone's favorite online mega-retailer sells both models directly.
Amazon never sells Pixel 3 – you can see the phone there, sure, but only from third-party sellers. All three colors of both 3a and 3a XL are now up for site orders, which are sold by Amazon itself. Acquired availability from Google Store, Verizon, T-Mobile, Sprint, Best Buy, and more, it's not hard to get your hands on a 3a.
If you want to get the Amazon, you're probably waiting for a moment. In writing, there is a 3a XL available in Clear White. All others say they will be sent within one to three weeks.
