Crysta is more cost efficiant then Card?? (In game purchase notice)

[Mysticales]

So today, wanted to get my 2nd retainer purchase. I have 420 Crysta in my account, but needed 473 to sync it up to my game time. Darn!

Well I would have to pay 5$ to get the 500 Crysta in there, which would do it. I was thinking, let me try via CC instead so maybe it only charges the pro-ratred amount to sync. (Like how it works with Crysta)

Turns out, it wanted to ring me up for 5$ to pay for the retainer... Thing is... With Crysta it only costs 473.. So basically a 30 cent more cost if I did it by card alone.

Kinda sneaky, so I thought I would post to people here that if they want extra retainers. Stay with Crysta. Comes out cheaper it seems.

Last I knew time cards were game time only and didn't cover retainers, or you talking about credit card vs crysta? I personally not going to worry about about a 30 cent difference.

Im talking about using a card to buy crysta (Vs attaching a card to the system)
While the above is just one example. What if it could have gone as high as 1$? I cant check that since I was basing it on my gametime sync for hiring a retainer.
