Amazon’s Prime Big Deal Days sale is proving a decent source of Steam Deck accessory deals. Last week’s early offers shaved cash off some of my personal favourite cases, docks, and microSD cards, and now that the main event is underway, there’s a fresh supply of affordable add-ons for the Valve handheld. Here, we shall catalogue the best.

Since Prime Big Deal Days is basically a second Prime Day, it runs with the same rule of all the biggest savings being limited to Prime members. If you’re not one, you have two choices: wait and take your chances on the inevitable Black Friday sales in a few weeks’ time, or sign up for the free Prime 30-day trial. The latter option won’t cost a thing if you cancel before those 30 days are up, and that’s more than enough time to nab some Steam Deck accessories on the cheap before the end of Prime Big Deal Days on October 11th.

Without further ado, here are my picks, split into microSD card, docking station and case deals. We’re also tracking Prime Big Deal Days’ best graphics card deals, and for a complete overview of all things hardware, check out the main Prime Big Deal Days PC gaming deals hub.

Best Prime Big Deal Days Steam Deck microSD card deals

A microSD card is inarguably the first and foremost Steam Deck accessory you should be securing. Even the top-spec model's 512GB SSD will run out of storage in short order, and there are many individual games that simply won't fit on the base Steam Deck's 64GB eMMC drive. A microSD card is an inexpensive fix, and judging by my testing, can usually do an impressive job of keeping up with the internal SSD on performance.

All of these will work well in the Asus ROG Ally and upcoming Lenovo Legion Go, too.

Best Prime Big Deal Days Steam Deck dock deals

The Steam Deck’s desktop mode is key to its flexibility: besides allowing it to literally work as a desktop PC, this mode is where you’ll unlock extra functionality that can benefit the default Gaming mode as well. If you want to install Battle.net or play PC Game Pass games on your Steam Deck, say, desktop mode will make it happen. And the best way of navigating desktop mode is with a mouse and keyboard, connected through a compact yet connectivity-rich docking station. Like these!

Best Prime Big Deal Days Steam Deck case deals

Valve bundle a hard case with every new (and refurbished) Steam Deck, making the need for a new one less pressing than that of a microSD card or dock. Still, the official case is a basic design, with no extra pockets or compartments, so it’s not above replacing – and there are couple of options for how you might do so.

One is to just get a more tricked-out carry case, with added capacity for bits and pieces like earbuds, the Deck’s charger, or additional microSD cards. Or, you could wrap your handheld in a form-fitting silicone case that adds protection – including while you’re actively using it – without adding much in the way of bulk.
