Ordering and payment
Can I place an order online?
Yes. Add an available product to the cart, complete checkout and choose Pay by Invoice, Zelle or Cash App. Manual payment orders remain on hold until the payment is verified.
Does an order confirmation mean payment was received?
No. The confirmation records the order and provides its reference number. You will receive a separate update when a manual payment is confirmed and processing begins.
Shipping and delivery
Where do you ship?
We provide free tracked shipping to all 50 U.S. states.
How long does delivery take?
Orders with confirmed payment received before 2:00 PM Eastern Time on a business day are handed to the carrier the same business day. Standard transit is estimated at 2–3 business days after carrier handoff. Orders confirmed after the cutoff, on weekends, or on U.S. holidays begin processing on the next business day. APO, FPO, and military destinations may require 2–4 weeks. Delivery estimates are not guarantees.

Can an item be returned?
Eligible unopened, unused and sealed products require an RMA requested within three days of delivery. Review the Return & Refund Policy before sending a return.
