I was trying to buy the for 169,400 sp but I keep getting an error page saying "You don't have enough sp for this item" every time I have tried to buy it. I definitely have enough sp on hand though.

Are you absolutely sure you have and invite turned in? Because I just checked and I'm not having this issue.

Yes, I'm sure. It wouldn't let you into the shop if you didn't redeem it if i'm not mistaken.

That is correct. I would suggest filing a ticket though unless more people pop up with the same issue.

Hm, okay. I'll probably wait and see if anyone else has the same problem for a bit but if not then I'll file one. Thanks :)

I was clicking the "go back to the last page" button. but I think whatever was going on might be resolved now because I was able to buy another item.
