Grab a 400GB/256GB SanDisk microSD card from Amazon and save up to $140
Per the Amazon listing, the SanDisk Ultra 400GB micro SDXC UHS-I is now available for a palatable $109, boasting $150 in savings on the usual $250 price. When this microSD card hit storeshelves in 2017, it was the biggest one around, and although we've seen the capacity increase since then, this 56% discount on SanDisk's 400GB is still quite the sweet deal for those looking to double, triple, or quadruple their phone's storage.
But if 400GB (plus whatever your device's default ROM provides) seems like overkill, perhaps you should consider the SanDisk Ultra 256GB microSDXC, which is now going for $55, instead of the regular $78. And if that's too much as well, then there's the 200GB option, which is down to $41 from the usual price of $51. If, by any chance, you want even less storage, check out the other SanDisk deals that cover everything from the company's tiny 8GB card, up to the $400GB monster.
Before you jump the gun and hand over your hard-earned cash, though, do make certain that the gadget you intend to kit out with this microSD can actually make use of it. Some devices, particularly older / lower-end models, are not designed to handle newer, higher-capacity microSDs.
