COSMO tip
Returning the watch itself doesn't cancel your service plan — those are two separate actions, so make sure you cancel the plan through the parent portal too or you'll keep getting billed.
Deux par Deux tip
Choosing store credit over a cash refund gets you a 10% bonus — worth it if you know you'll be buying the next size up soon anyway.
