Frequently asked questions
Why ask for phone during checkout?
A phone number gives the carrier and support team a contact path for delivery exceptions or order questions. It is stored with the fulfillment details. Promotional SMS consent, when offered, is separate and optional.
For your first order: compare products, check out, then use your order number if you need support.
