You can get these unopened, new for not much more. A notable issue with the M2 MBAs was that the base 256Gb had storage configured on a single chip, which halved the SSD performance speed over the M1 that used two 128Gb chips. I ended up returning base MBAs to Costco and bought a model with 512Gb storage and confirmed that storage read/write speeds were up to 2800Mbps like my Mac Mini M2 Pro.
Just be aware of this idiosyncrasy with the M2 MBA before purchase.
