Why is my credit card authorized for more than my order confirmation amount?

When you place an order on idex-hs.com, your credit card is authorized, not immediately charged. Here’s how the process works:

Initial Authorization

  • At checkout, we authorize your credit card for:
    • Product total
    • Applicable tax
    • Estimated freight
    • Plus a 15% buffer to account for shipping or tax adjustments
  • If all items are in stock, you will typically see one authorization, which will then settle for the final charged amount.

Orders with Back‑Ordered Items

  • If your order includes back‑ordered products, you may see multiple authorizations.
  • Credit card authorizations expire after 7–10 business days.
  • When an authorization expires and items are still open on your order, a new authorization is sent that:
    • Covers all remaining open product and freight lines
    • Subtracts any already shipped (closed) items
    • Includes the 15% buffer

Partial Shipments and Additional Authorizations

  • To provide faster delivery, we now ship partial orders.
  • Back‑ordered items are released as inventory becomes available.
  • When a back‑ordered item is ready to ship and the existing authorization does not fully cover the cost:
    • A new authorization is placed for that item’s cost, tax, freight, and the 15% buffer
  • This process continues until all items on your order have shipped.

Important to Know

  • Authorizations are not charges and will drop off your statement if they expire.
  • You are only charged for items as they ship.
  • Multiple authorizations may appear, but the total amount charged will not exceed the cost of your order.
