In the year 2006, DTI released an administrative order about the price tags and labels that is being used by most retailers. Attached in this post is the softcopy (PDF format) of the administrative order by DTI. This order will be beneficial to credit card users who prefer to by an item in installment mode, as it would mean that the card price is equal to the cash price, as well as prevent other surcharges being imposed by retailers. Save a copy of this if you want to, you may need this in the future :)

Very informative post!
