UPDATE- last week i went there again and they have solved the out of date goods problem by making all the labels hand written with only what the item is and price.
I thought i would risk it and bought a US sirloin steak, cooked it on the BBQ to medium and to my horror i could hardly cut it with a steak knife let alone chew it.
It was a good day for our dogs.

 

I'm afraid that it's not just in Philippines were this happens and I think it is a deliberate ploy to mislead people.
Even my favourite stores in UK, have sadly started to use similar "sales technique "
eg; Soap powder= big box less powder, pack of four tinned beans costs more than buying separately
Deliberately not pricing goods so you will buy them at the till anyway.
Good point made there CharlyB
