barca x coldplay presale

I want to surprise my boyfriend for his birthday with a barca x coldplay jersey since lewandowski is his favorite player and coldplay his favorite band.

I signed up for the barca x coldplay presale but am very confused how this works. I had originally assumed I would get an email since one is required to sign up, then figured I should keep the tab open with the countdown, but now the countdown is over and the sale starts in 20 min but I have no idea what to expect, how to access it, anything.

typically I would take some more time to research or scour the internet but only found out about this today and spent all day at work and have not had time.

If anyone knows or has an answer, let me know.

Thanks

Edit: despite still having the page open that says I am registered for the presale, every time I refresh it in a new tab it tells me that the presale registration has ended. Is anyone else having this issue or is anyone having better luck with the presale?

Edit 2: Finally made a decision to order a T-shirt size M, not sure if their shifts fall big, small, or true to size. quite anxious that I got it wrong but also uncertain if the return policy applies or has caveat with it being a limited edition item if I ordered a second one in L to be certain.
