Not sure about the financial part of it, but I do know that it was never obligatory to pass on the saving.
Not all shops passed it on at the time and a lot of those that did seem to have quietly dropped the discount since after Christmas.
Because it ended up with weird prices, and I think most shops, if they havn't completely abandoned the discount, have round their prices up by now at least (so you don't get things that cost £23.54 for example)
