I think the main retailers really need to be reigned in.  

PicNPay for example has "SAVE" stickers on items at higher prices than they were the week before (in the case of milk.)  Or SAVE stickers on items if you buy all three, except you only need to buy one item at the same price if you bought all 3.  It is truly misleading practice which entices those desperate to save into spending more.   

I think it is time to take them on and bring in more stringent laws to protect the consumer - like they did in the UK after the same practices were used on the consumer.
