Question about plat

So basically when a 40% plat sale is on, and I say I wanna buy 400$ worth of plat, does the sale only work once so for example I buy the 100$ plat package at 40% off and say I also wanna buy another 100$ package after that will it also be 40% off or only works for one package and the sale goes away.

I'm new to the forums so I don't really know much things.

Actually theres a particular period when the sale is on. During that time no matter how many times u buy plat packages the off still remains 40 percent. Once sale off then the offers return to their originals.
