Ground Zero Games will be closed for a short while.
From their website:
Please note we will be closed for a one-week short break from Friday 28Th May (today) until Monday 7Th June. Sorry about the lack of advance notice on this, we had planned the break for later in June but for various reasons have had to bring it forward. The online store will still be accepting orders, so you can still place them if you wish, but nothing will get shipped out until we re-open on the 7th (of course, your card won’t be charged until we ship your order, as usual) – as soon as we are back we will clear any outstanding orders as quickly as possible. All orders placed up to the morning of Friday 28th have been processed and mailed, so if you’ve already put your order in then it’s on its way to you.
