You probably haven't owned that USB Type C cable long enough for it to fall apart yet, but that doesn't mean there's no reason not to stock up on a few more. Right now you can grab a couple on Amazon from Cambond for a solid price. These are C-to-A cables, the kind you need to plug in a USB Type C device with something still sporting an older USB port.
The cables are braided, so they should feel better in hand than the cord that came with your phone. The 1ft option starts off at $10.99 but goes down to $6.99 with the code MZMJTT8L. The 6.6ft cable goes from $12.99 to $7.99 with WUYZF28W. Both are only available in gold, so you can wear them around your neck when not in use.
A 10ft cord tops the list. It starts at $18.99 and drops down to $8.99, which is over half off. To get the savings, you need to enter FPJHB8CF at checkout. This one comes in gray, silver, or gold.
