Nobody answered our invitation to win a $5 coffee card on us, by proving that a retailer is adding the new credit card optional surcharge.

Our first blog entry laid out the terms.

The offer stands.  If you can show by photo or other means (even a credit card receipt) that some retailer (after Feb. 1) began adding the surcharge, as permitted by a court settlement of a class action suit, then you'll get one of three cards we're offering to readers.

Read that entry to get the particulars. Limit, one submission per person.

We weren't confident that any retailer would start doing something that few others would. Still, we wanted to test that theory by asking the mob for any indication if it is or isn't happening.

We'll have a package of stories about the changes and tips for credit card users this Sunday in Business.
