Shipping policy
FROM CHECKOUT TO YOUR DOOR
Effective date: August 13, 2026
This is the U.S. shipping policy for orders placed at isaacstratosys.shop.
WHERE WE CURRENTLY DELIVER
Our current sales area is the United States. Eligible delivery addresses within the 50 states and Washington, D.C. can place orders when a shipping option is available at checkout.
Service to P.O. boxes, APO/FPO/DPO addresses, and U.S. territories depends on the product and carrier. If checkout does not offer a shipping method for an address, we cannot currently accept delivery to that location.
We do not currently ship internationally.
SHIPPING COST
Shipping charges are in U.S. dollars (USD) and are shown at checkout before payment.
- Orders with a merchandise subtotal of $80.00 USD and under: standard shipping is $15.00 USD.
- Orders with a merchandise subtotal of $80.01 USD and over: standard shipping is free ($0.00 USD).
There is no minimum order value. Orders of $80.00 USD or less are accepted and shipped; the $15.00 USD shipping fee is added at checkout.
Applicable sales tax is calculated separately and is not part of the shipping charge or the $80.01 USD free-shipping threshold. The shipping amount shown at checkout is the complete merchant shipping charge for that service. We do not add an extra courier surcharge on top of the rate displayed before payment.
These rates apply to standard U.S. shipping only. The destination, shipping cost, processing time, and transit time on this page are intended to match checkout and the shipping settings submitted to Google Merchant Center.
THE TWO PARTS OF DELIVERY TIME
Every order passes through two separate stages:
- Processing: checking payment, confirming inventory, preparing products, and transferring the package to a carrier.
- Transit: the period between carrier acceptance and delivery.
Order cutoff time: 6:00 PM Eastern Time (ET).
Orders placed after 6:00 PM ET generally begin processing on the next business day.
Order Processing Time
Orders are normally prepared within 1 to 5 business days. Weekends and U.S. federal holidays are not business days.
Transit / Shipping Time
Unless a different estimate is displayed before purchase, standard carrier transit generally takes approximately 5 to 15 business days after the order has been shipped.
Total Estimated Delivery
Combining processing and transit, most orders arrive within approximately 6 to 20 business days from the date processing begins (subject to the 6:00 PM ET cutoff).
These are reasonable estimates, not guaranteed arrival appointments.
ONE ORDER, MORE THAN ONE BOX
Items from the same order may be prepared at different facilities. As a result, one order may produce multiple packages, tracking numbers, or delivery dates. A split shipment does not create an additional shipping charge unless that charge was clearly disclosed before purchase.
THE TRACKING HANDOFF
When tracking is available, we send it to the email used during checkout. A newly created tracking number may require 24 to 72 hours before the carrier displays movement.
PLEASE CHECK THE ADDRESS TWICE
Customers are responsible for entering a complete delivery address.
If you notice an error, email service@isaacstratosys.shop immediately. We will try to make the correction, but an address cannot always be changed after processing or shipment begins.
A customer may be responsible for reasonable additional shipping costs caused by an incorrect or incomplete address supplied with the order.
WHEN TRACKING SAYS “DELIVERED”
If a package is marked delivered but cannot be found:
- Check the mailbox, porch, side entrance, parcel locker, and other safe drop-off locations
- Ask household members, neighbors, reception, or building management
- Allow until the end of the delivery day
- Contact the carrier using the tracking number
- Email us if the package remains missing
We may request carrier information or other documentation before determining an available solution.
DAMAGE DURING DELIVERY
Keep the item, packaging, shipping carton, and label. Email service@isaacstratosys.shop with the order number and clear photographs so we can review the situation.
A damaged package should not be discarded until the review is complete.
WEATHER, CARRIERS, AND OTHER DELAYS
Weather emergencies, transportation interruptions, holidays, address problems, security reviews, and carrier congestion may affect delivery.
If we cannot ship within the time promised at checkout—or within 30 days when no shipment time was clearly stated—we will notify you and provide the choices required by applicable law. Depending on the circumstances, you may agree to a revised shipping date or cancel the unshipped order for a full refund.
CHANGES AND CANCELLATIONS
Send cancellation or correction requests immediately. We cannot promise a change after fulfillment begins.
A shipped product is handled under our Return Policy.
