1-year PS Plus membership for US store

When I purchased PS4, I bought two 1-year PS plus membership codes for US-store.

It can be stacked. I sell the code SGD 60 each. Thanks.

Here is the way that I propose to deal the PS plus membership. When we deal
face-to-face, we first check the expiration date of your current membership,
then I redeem the code on your smartphone (I think we can redeem codes from a
web browser), then you check the updated expiration date and make the payment to
me.

If you are interested, you can SMS 93501782. I will contact you as soon as possible
