How to get Carbon38 cashback, step by step
- Open TopCashback's Carbon38 page and click through to Carbon38 from there. That click is what ties the order to your account, so start every Carbon38 order this way rather than from a bookmark or a search result. The rate as we last read it was 10%.
- Shop in that same tab and session. Don't leave for a coupon site and come back, and turn off any other cashback or coupon extension before you check out: the last click before the order is the one that gets credited, and another extension's click can take it.
- Check out in one go, using only codes TopCashback itself shows for Carbon38. A code from somewhere else can void the cashback on many stores.
- Wait for it to confirm. No fixed window. Cash back goes pending, then confirmed once the retailer reviews the order, then payable once the retailer's network is invoiced. TopCashback prints an estimated payout speed on each merchant's page. Returning part of the order, or cancelling it, changes what gets paid.
- Get paid. TopCashback pays by: Bank transfer, Venmo, PayPal, gift cards, a Virtual Visa Prepaid Card or an American Express Virtual Reward Card. Minimum: None for PayPal, Venmo or bank transfer; some gift cards have one. Timing: On request, once the cash back is payable. Adding bank, PayPal or Venmo details puts a 72-hour hold on the account first.

How these Carbon38 numbers were produced
- Read directly from each portal's own merchant page, never copied from another comparison site.
- A rate we could not read is reported as unread. It is never converted into a zero, and a failed check never overwrites a previously good number.
- "Up to" and new-customer-only rates are labelled as such and are not allowed to win the top spot over a lower rate that everyone actually gets.
Carbon38 cashback FAQ
Which portal pays the most for Carbon38 cashback right now?
TopCashback, at 10%. That's the rate a returning shopper gets, which is how the table ranks: an "up to" ceiling or a new-customer rate never takes this spot over a lower rate everyone gets.
How long does Carbon38 cashback take to pay out?
On a click-through portal there are two waits, one after the other: the portal has to confirm the order with Carbon38, which mostly tracks Carbon38's return window, and then the confirmed balance has to be paid out, which is the portal's own rule. Buying Carbon38's gift card through a portal skips the first wait: that cashback is paid when the card is bought.
