Thanks to a lucky break, my balance went negative. The cashier deducted the full regular price for the free body wash, instead of the discounted $3.88 price.  As a result, my balance went negative ( - $0.23).  When tax was added, the final total came to $0.41.  I spent 3.00ECB and earned 3.00ECB.  Card3 remains with a 14.99ECB balance.
