Where Is My Order?

In-stock items will normally ship within 2-3 business days of your order being processed. Most orders are delivered within 10 business days of order placement. If your order has been delayed, it may be due to the item being out of stock or due to peak season delays. We normally ship in-stock items first, and then we ship the out of stock items at a later date.  

Please email support@stemfinity.com with any questions regarding the status of your order. 

Problem With My Order

Order is delayed – Contact us.

Problems after delivery – Carefully inspect the contents of your order upon delivery.  Small items may have settled and may be hidden at the bottom of the box.

If you find a problem, please contact us immediately.  We want to remedy the situation as soon as possible.  Depending on the carrier, we may not be able to track shipments, obtain proof of delivery, or file for damages for orders that have shipped more than 60 days prior to contact.  

  1. Damaged items – Keep all shipment and product packaging material for inspection by the carrier.
  2. Need to return merchandise? – Contact us first! Learn more about returns.
  3. Missing items – The item may have been out of stock, back ordered, or shipping separately from a different warehouse.  Please contact us about items missing from your order.

Non-U.S. Addresses: Ordering & Shipping Considerations

We cannot process your order on our Web site if:

  1. Your credit card billing address is outside the U.S. or
  2. You want your order shipped to an address outside the U.S.

These orders must be placed over the telephone. Please call (657) 444-7836 or (800) 985-7836 from within the U.S. during our business hours, Monday through Friday from 8:00 am to 5:00 pm Mountain Standard Time to place your order.  

Some items we offer are only available to U.S. customers.  Please contact us for details. 

Shipping to Addresses Outside the U.S.

If you wish to have your order shipped to an address outside the U.S., our staff must first verify items can be shipped out of the U.S., then quote the shipping and handling charges. For the most accurate shipping quote, we require the full shipping address. Within 3-5 business days, we will send a shipping quote to the e-mail address you provide. (It is essential you provide a valid e-mail address when you call.) Before we can process your order, you must reply to our e-mail and confirm that the shipping and handling charges are acceptable, then schedule a time to process prepayment for the order. 

Our normal policy for international orders is to hold the entire order if an item is out of stock. Please contact us if you would like your order partially shipped.  This may result in increased shipping costs.

For any order that is shipped outside the U.S., the purchaser must prepay with a credit card and agree to be responsible for all shipping and handling charges as well as any import tariffs, taxes, duties, broker fees, or any other associated charges.

Note: STEMfinity will not be responsible for delayed, damaged, or lost international shipments.

Out-of-Stock Items (Back Orders)

An item that is temporarily out-of-stock has been ordered from our supplier but has yet to arrive at our warehouse. Even though the item is out-of-stock, you may add it to your shopping cart.

If your order contains both in-stock and out-of-stock items, we will ship the in-stock items right away, generally within 24 hours of your order. The out-of-stock items will ship as soon as they become available.

If you would like your entire order held until all items are available, please specify this in the Comments field of the Checkout page.
