Amazon has been revealing the heavy discounts on its own tech products in the build up to Prime Day, which starts at 6pm today, Monday 10 July. One of the standout deals is for a Fire 7 tablet for just a penny shy of £30.

The latest Fire 7 tablet, reviewed here, was already a bit of a bargain at £50, but with a further £20 off the price until the end of Tuesday 11 July, it's easily the best value tablet device on the market. There are two versions of the Fire 7 available, one with 8GB of storage and one with 16GB. Only the 8GB version is being discounted. 

It has a 7-inch 1024 x 600 resolution screen, 1.3GHz quad-core processor and 1GB of RAM. The £50 model comes with 8GB of storage, but it also has a microSD card slot that is capable of expanding that by up to a further 256GB.

It runs on Fire OS, which has many of Amazon's own services hardbaked into the system - such as access to Amazon Prime Video for Prime members. And Amazon Underground provides thousands of apps, games and in-app items for free to all Fire users. There's also now built-in access to Alexa, Amazon's personal assistant. 

There is a 2-megapixel camera on the rear and a VGA camera on the front. It comes in black, blue, tangerine or magenta.

The deals on Fire tablets don't end there, though. Amazon is shaving money off the rest of the Fire tablet range, too. You will be able to pick up the Fire HD 8 tablet, which, as the name suggests comes with an HD display, for £50. That's a huge saving of £30. 

The Fire HD 8 also has Alexa built-in, but improves in practically every other area over the Fire 7. A 1.3GHz quad-core processor remains, but it's boosted with 1.5GB of RAM and 16GB of storage as standard. There's Dolby Audio onboard too for improved sound performance.

Kids can get in on the Prime Day action as well, as Amazon is discounting the Fire 7 Kids Edition and the Fire 8 Kids Edition tablets. Both tablets are made tougher than their Fire 7 and Fire HD 8 counterparts thanks to a rubberised case, and the operating system has been stripped back to make it more appropriate for youngsters.

They come with included access to Kindle for Kids, which offers access to age-appropriate content from apps, to videos, to books. You can get a Fire 7 Kids Edition for £70, a £30 saving, or a Fire 8 Kids Edition for £90, representing a saving of £40.
