SanDisk 512GB microSD Express card drops to $91 for Switch 2

The SanDisk 512GB MicroSD Express card is $91.05 at the official Newegg store on AliExpress with coupon code DBDEAL20, and that is the price worth a hard look if your Nintendo Switch 2 is already chewing through its onboard space.

Deal	Price	Usual	Store	Ends
SanDisk 512GB MicroSD Express	$91.05	$129.99	AliExpress via Newegg	Limited time

SanDisk 512GB at AliExpress via Newegg ($91.05): Buy it if you need Express storage and the coupon still applies. The listing shows $129.99 before the $20 off code DBDEAL20, a stated 30 percent cut, local U.S. shipping from the Newegg storefront, and delivery called out as within about a week. Newegg is described as an authorized SanDisk reseller. I squinted at the banner math; the catch is the coupon and the limited window, not a mystery fee in the copy we have. Speeds are listed up to 800MB/s, and a 512GB card triples the Switch 2’s 256GB onboard storage. Verdict: verified, with a catch (code required).¹

SanDisk Gameplay 512GB at Costco ($89.99): Buy it if you already pay for membership; skip the signup math if you do not. Free delivery is stated, and the card is called out as probably very similar, if not identical, to the Newegg SanDisk. Members-only is the whole catch. Verdict: verified, with a catch (members only).¹

Samsung P9 512GB at Amazon ($99.00): Wait unless you want Amazon fulfillment more than the last few dollars. Usual price is listed at $149.99 (34 percent off). It costs more than the SanDisk coupon price and the Costco member price. Verdict: verified, not the low.¹

Switch 2 storage is the reason these cards matter. The console ships with 256GB (about 249GB usable after system software in one account of the space), and it accepts only microSD Express—not the ordinary microSD cards from the original Switch, except for importing old screenshots and clips. Save data stays on system memory. Nintendo supports Express cards up to 2TB, recommends one card at a time, and sells none in the box. Large digital titles on the order of Final Fantasy XIV (~117GB), Final Fantasy VII Remake Intergrade (~90GB), and other 40–70GB releases fill the internal drive after a few downloads. Express is the faster standard the system is built around; “Extreme” branding is not the same thing.¹²

Flash pricing has been jumpy enough that one write-up framed a mid-$90s SanDisk 512GB as a rare break against a storage squeeze, and IGN’s own desk floated the same $91 card with no promise of a deeper Black Friday cut. @IGN pointed readers at the $91 Newegg path as a straight triple of Switch 2 space.¹³

These prices were as listed when this ran and may change.

Our read: The real deal is the one that matches a card you already needed: $91.05 with DBDEAL20 is a checked cut from $129.99 on a Switch 2–required Express part, Costco’s $89.99 is the member floor, and $99 at Amazon is the comfort premium—not the win. “Limited time” and a coupon are doing the work; verify the code still fires before you treat $91 as locked.
