Is it possible to increase my limit, I bought a couple boxes when equinox was out. Noticed that the diamond boxes were out and was wanting to get one but am unable to buy since there is a limit. I run Spiral Knights through steam and my ID is https://steamcommunity.com/profiles/76561198301042870.
You can write to the support team and make a formal request. I don't know much about it, but my sense is that they will increase spending limits sometimes (if they think that the spender has their spending under control).
