if you’d like to change the number of packs, just choose the same pack but with the number of pairs you’d like to have.
Why do I need to go through this?
The reason why we ask you to go through checkout is that your bank or Paypal both need to have a confirmation from your side that it’s a change you indeed want to have.
When will I be charged?
You’ll be charged at your regular renewal date
Can I add tracking or remove it?
Yes, just choose that shipping method at checkout.
