I'm very interested in trying to win this, but being it is a UK code I think that is a issue. I just googled about this and Even though PS4 games are Region Free it seems as if Codes are Country Locked.
US codes only work on a US PSN account. I have a Link I am going to Post so the seller may review it. I did not think it would be a issue either and I even Bidden a decent amount. Then deciding to double check I found out this information.
From what I have read you may be able to set up a UK account and it work that way on your ps4, but that requires making a new profile. I am Just trying to Help so I hope you do not take offense to this. This PS+ cards go for a ton of credits and I'm sure you would hate to know someone was unable to use it. Again I am going to post the Link to where I found this Info. The topic,Questions and answers come straight from the PS forum.
As I said though and you all can google yourself or read the Links I posted.
U can still use the Code but you will have to make a different profile and set it up as if you were In the UK. Which Im almost sure even if you do that You can still have access to PS+ when signed in to your main account.
I'm not sure though, On the PS3 at one point in time you could setup a China account and use the 13day PSPLUS trial and it would work for all accounts.
@ Seller, to whoever wins this, If for some reason it would not work on a US account, Are you going to be willing to refund the Credits?
I am willing to still BID and give it a Try but If it does not work, even if making a UK profile to enter the code, I would want my Credits back.
Just a question. Since you Posted Yes it will work, And now after Finding out the issue with UK ps+ Codes You may want to mention that in your description.
