Keep the value of
what you already own.
Verify your purchase email. We check eligible payments and show your bundle price before you open checkout.
Credit reflects eligible payments after discounts and refunds, excluding tax and shipping. Duplicate kit purchases are not counted twice. Prior bundle upgrades carry their eligible purchase value forward. Credit is capped at the bundle price, has no cash value and cannot be combined with promotion codes. Purchases must use the same verified email; contact support for company purchase records under another address.
