Hello, I am new to this. recently I won around 200k zSilver now I want to redeem for few stuffs, I wanted to get Lancehead TE but it says its out of stock while it is in stock on Razer physical store, any help there? Also if I redeem for Razer Ornata right now, do I need to apply the voucher now? I mean does the voucher has any expiration date? thank you.
