Ponds Spf Duo Pack (EXPIRED)

Manufacturing date 250708

I was meaning to buy a new sunblock for my face. I heard many good reviews about neutrogena waterlight so i went to watsons to buy one,but i saw ponds was on sale! they have promo packs that was so hard to pass up!
Neutrogena was sold Php460 or $10 each,but the Ponds flawless white sunblock was on BOGOF! Buy 1 Get 1 FREE! for Php 199 or $4 for 30ml each. The rest of the Flawless white line is also on sale,and some Pond's age miracle products.
I purchased Ponds.thinking that i got a good deal,i opened it when i got home
Shesh ka bob! Manufacturing date at the back was 250708!! I know that facial products including sunblock has a shelf life of one year only. I got ripped off!!!
What should i do with this?! You would not see the expiration or the Manufacturing date unless you open the box,and the box is sealed,the inner box was also sealed with a plastic.
Please tell me Ponds your not putting expired products on sale.its so misleading!
