B&H is currently running a sale until tomorrow on one Google Pixel 3 XL SKU. The 6.3-inch phablet is only available at this special price for the Not Pink variant. You will not be tied to a carrier though. The SKU originally cost US$999 and is still US$799 on Google, but B&H has reduced it to just US$649.
