[Amazon/Newegg] SanDisk Ultra 128GB Dual Drive (USB C + USB A) for $49.19
- 34% off
This drive is at its lowest price according to CCC.
If you have an older phone though, SanDisk does make a drive with both micro-USB and USB 3.0 connectors, currently retailing for $48.65 at Amazon and $54.99 at Newegg. This is not on sale though, so it is not as good a deal as the USB C variant. For reference, the lowest price this has gone down to is $33.99, so I'd wait for this to go on sale, if you don't need the micro-USB version immediately.
