This is exactly the halacha had the overcharge been exactly 1/6 that the
deal is on but the overcharge gets returned.
Nevertheless SA stresses that 1/6 means that exactly and a change of one
"penny" would change the halacha.
Yet according to the SMA (as Micha intreprets it) actually this halacha
applies for a range between 1/6 of the starting price and 1/6 of the
final price.

Personally I am disturbed at defrining Onaah as exactly 1/6 to the penny,
meaning it is very improbably.
So from my viewpoint I am happy with this intreperation. Nevertheless
it doesnt seem to agree with SA.
