The balance came to $0.50, plus an additional $0.17 in local tax, for a grand total of $0.67.  I spent 2.50ECB and earned NONE.

However, I located expired merchandise in the store, and in lieu of issuing the standard "$2 OFF COURTESY COUPON", the casheir merely issued a 2.00ECB.

After 3 consecutive transactions, Card1 has a balance of 4.00ECB.
