Okay one; . It has been established that just putting in the actual number is perfectly fine and preferred.
Two; $.12 seems like a nonsensical code. Based on the (dumb) code systems the paid amount would either be 112 dollars ($=100 system) or 12 dollars (1.00= 100 system)
Which is why the codes are beyond dumb, they can be read 50 different ways and still all be wrong.
BTW this is not an attack on TC, he did his best, just pointing how the codes are dumb
