The balance came to $0.31, plus an additional $2.72 in local tax, for a grand total cost of $3.03.

This transaction was a comedy of errors, though.  First, the cashier only deducted 7.00 for the "free Quench coupon".  I didn't notice this until after the transaction and since my non-tax total was so low (31 cents), she offered to issue a 1.20ECB.  That was fine by me, since I knew that it would automatically round up to 2.00ECB.

Second, the ECB for the Specialty BandAids did not generate.  There is a 2.00ECB offer for the entire month of December, but the quantity pricing is messing up the ECB.  The BandAinds are priced @3.59, but when you buy two they are only $3.00 each (2/6.00).  The ECB is 2.00ECB on a 3.59, so that must be causing the problem.  I had to get two 2.00ECB (4.00ECB total) manually printed.

So, I spent all 19.34ECB and earned back 10.99ECB (4.00ECB for BandAids, 2.99ECB for EOS, 2,00ECB for Olay, and 2.00ECB for the Quench "error").

Card3 then had a balance of 8.99ECB as I made a second transaction.
