Nah, it's limited for a reason. It won't become fair to all of the early buyers to give others a chance to get a limited item. If you weren't around or didn't buy it at the time--oh well.
I've seen a lot of people talking about wanting the bitsplosion effect lately. The effect has been around for a while, it was always good-looking, but people never really discussed of having it back--until now.
It's just like any limited offer irl. You can buy it for this amount for a limited time or have limited units of the item you're buying. That same thing is for this pack
