Amex slightly changes their rewards program

I just noticed that American Express lowered one of the tier of their Cash back program. Please read the NOTICE at the end.

Rebate percentages for each Rebate Year are as follows: For the first $6,500 of Eligible Purchases (as defined below), the rebate percentage is 1% for Everyday Purchases (as defined below) and 0.5% for all other Eligible Purchases.

For Eligible Purchases of $6,500.01 or more, the rebate percentage is 5% for Everyday Purchases and 1.5% for all other Eligible Purchases.
"Everyday Purchases" are Eligible Purchases made at U.S. supermarkets, gas stations and drugstores, in each case that are not departments of superstores or warehouse clubs.

"Eligible Purchases" are charges to your account for goods or services that have not been returned or otherwise credited to your account.

Eligible Purchases do not include Finance Charges, fees, Cash Advances or other means of accessing your account, convenience checks, Balance Transfers, or the purchase of American Express® Travelers Cheques and American Express® Gift Cheques or other cash equivalents.

Additional terms and conditions apply.

NOTICE: Changes to the Rebate go into effect June 1, 2009 - The definition of Everyday Purchases will be updated to include Eligible Purchases made at the following categories of U.S. merchants that are not departments of superstores or warehouse clubs: supermarkets, drug stores, and automobile gasoline stations (for purchases of automobile gasoline only, except that any purchase in excess of $400 at an automobile gasoline station will not qualify as an Everyday Purchase).

In addition, after the first $6500 of purchases made annually on the Card, the rebate percentage of 1.5% will be reduced to 1.25%.
