Question about MP Vendors

[Elemental]

So today, me and my girlfriend went to the Testing area for easy portal access and we noticed the Reward Dealer, where we noticed the Portable Holes. We bought a few of them and were surprised we even could buy them!

But I'm assuming it costs MP, even though it doesn't display a cost next to it.
So, I was wondering, is there an overview somewhere displaying all the costs of the items in the Testing Area, most specifically the Reward Dealer ?

Hi there,
You need our client to be able to see MPs and the cost etc since they are a custom currency.
Check the download section of the website, get out client and always start using the Launcher.
