Clear membership has $15 cashback on C1S—can you get a higher offer?

First, check whether the cashback terms exclude member reimbursement-type spending, so you don't waste your time.

For this $15, you need to check whether the C1S cashback excludes orders that were reimbursed with Amex, and whether renewals after membership expires count as new orders. If someone has seen a higher rate, it's most likely a limited-time promotion, so before placing an order, make sure to check how long it stays pending and whether it's calculated on the net amount.

First, screenshot the terms for the $15 offer—focus on the payout timing and excluded categories—then decide whether it's worth waiting for.

If you were planning to renew Clear anyway, you might as well lock in the current offer first—as long as the cashback terms don't exclude this purchase.
