it's simple. if your in the builders club and your friends wanna buy somthing, you can give them discounts if you want. like it somthing is 50 robux and 70 tickets you can give them a 30 robux discount and a 30 ticket discount to a total of 20 robux or 40 tickets. yes or no?
I don't think so. If you wanted, couldn't you update your shirt for a low price, then tell them to quick, buy it - then put your price back up?
That would be a discount, and you wouldn't lose much.
Otherwise, I still don't see why you should bother.
