Shipping & Delivery
Shipping & Delivery
Priority door delivery, 2–4 business days
Every order ships priority from our U.S. warehouse and arrives at your door within 2–4 business days across the continental United States. Delivery is free on every U.S. order. The price on the product page is the price you pay at checkout.
Where we ship
We ship within the United States only for now. International shipping opens later — write to support@sinpremium.com and we will tell you when.
How it moves
Orders are picked, inspected and handed to the carrier within 0–1 business day. Tracking reaches you by email the moment the parcel moves.
What actually arrives at your door
An outer carton carrying only our logo. No product description, and nothing on the label that says what is inside. The gold-foil SIN box is inside that carton, seen for the first time by you. The charge on your statement is equally discreet.
Lost or delayed
If tracking has not moved for 7 business days, email support@sinpremium.com with your order number. We chase the carrier, and if the parcel is genuinely lost we send a replacement at our cost.
Wrong address
Tell us within a few hours of ordering and we can usually correct it before the parcel leaves.
Returns
30 days from delivery — opened is fine for the restraint sets and instruments, and we pay the return shipping. Lingerie returns sealed and unworn, for hygiene. Full terms on our Returns & Refunds page.
