I did a (very) quick search and didn't see this, so here goes....
NASA FCU sent an email today about their cash rebate credit card that pays at the following tier levels:
Card Balance at End of Each Monthly Billing Cycle -- % cashReward
$0 - $1,000 -- 1%
$1,001 - $2,000 -- 1.25%
$2,001 + -- 2%
The reward disburses annually in Novmeber. I've heard elsewhere that NASA is pretty liberal with issuance and was an exclusive EQ puller when I last checked.
Terms [Warning: PDF] for the rebate program are as follows:
Rebate Program for Platinum Cards— The cash rebate is earned with purchases beginning on the first day in which the program begins and is paid annually to accounts open and in good standing on the posting date. Every dollar in net purchases (purchases of goods and services minus any returns or refunds) that a cardholder or any authorized user on the account makes with a NASA Federal Platinum Cash Back Rebate credit card, is covered by this program. The net purchases that appear on the monthly statement during the program period earn a cash rebate. All rebate accruals will appear on the monthly statement. We reserve the right to determine if net purchases qualify for the rebate. No retroactive rebates will be awarded. We reserve the right to prohibit any cardholder from earning or receiving a rebate. If an account is closed for any reason, membership in the program will be terminated and the total balance of accumulated rebate earnings will be forfeited. Membership in the program will be renewed automatically each year, as long as the account is open and not in default as described in this Cardholder Agreement, unless we are notified of cancellation. The balance transfers, cash advances, overdraft protection advances, convenience checks, money orders, finance charges, unauthorized or fraudulent charges, or fees of any kind, including fees for products that protect or insure the balances of the account are not eligible for rebates. Rebates will be deducted for any returns or credits made on the account. Rebates earned are not transferable and cannot be used as payment of obligation to us. The program and benefits are offered at our sole discretion. We reserve the right to alter or waive any program feature or benefit prospectively or retroactively, including, without limitation, participation fees, rebate accrual or criteria, or to cancel or temporarily suspend the program at any time. The program is void where prohibited by federal, state, or local law. These rules and regulations set forth all the terms of the program. We have no other obligation with respect to the program beyond those described in these rules.
Rebate is based on net annual purchases as follows:
a. 1% rebate for purchases up to $1,000;
b. 1.25% rebate for purchases from $1,001-$2,000;
c. 2% rebate for purchases from $2,001 +
, you could use it to pick up geeky chicks.
