How often does Nike offer discounts on their official app?

So i really need to get some new Metcons because mine are literally falling apart at the seams like the sole is flapping when i walk and i have this huge training camp thing starting in like ten days so i need them basically yesterday. I've been checking the nike app every single morning for the last week and everything is still full price it sucks.

I saw some reddit thread saying they do these Member Days sales like every few months but then another site said they do random flash sales on tuesdays so now im just confused and checking my phone constantly. I have about 110 bucks to spend and right now the ones i want are 150 which is just way over what i can do right now. Does anyone actually know the schedule for these things or is it just totally random? Like is there a specific day of the week they usually drop the prices or should i just give up and buy them full price before my trip starts? I dont wanna spend the extra cash if a sale is gonna hit in like 48 hours but i really cant wait much longer than that...
