Portal

First up, the flagship Portal, which scored a reasonable 79 in our review back in October. If you're not massively bothered by size, the eight-inch white mini model comes in cheapest at $92 instead of the usual $130. For the black, you'll pay a couple dollars more at $95. Go for the 10-inch version in black and its $145 instead of $179. The 10-inch white is a few bucks more, at $149. A big thumbs up here for the device's integration with Messenger and WhatsApp, plus its rich video chat features.

Portal TV

If you're looking to add video chat functionality to more than one TV set, Amazon is offering the Portal TV for $139 instead of the usual $149. This isn't the greatest deal ever, but again, you have the option to save $50 if you buy two or more products, so it could still be worthwhile if you're in the market for this device. We scored it 78 when we reviewed it at the end of last year, and were impressed by its wide field-of-view lens.

Portal Plus

The bigger, more expensive version of the Portal, Portal+ has come down in price anyway since its release, but Amazon now has it on offer for $249 instead of $279 (and again, there's that sweet $50 bulk-buy discount). It comes with a larger display that can be rotated between landscape and portrait modes as well as robust video chat features, although our review (where it scored a decent 83) did note some users might find it a bit too big. All these deals run until February 15th.
