Question about a purchase of platinum with discount

[Ygnaro]

Hi people! How is going? First of all sorry for bad eng.

The problem is next: Warframe reward's day give me a -75% of discount for platinum. I was print the coupon but I wasn't found branch office open in the weekend.
The question is: The discount in game ends in a couple of hours (only the weekend). I have the coupon with the discount, can I pay it tomorrow Monday and have the platinum with discount? Or because the discount ends today, I can't?

 

Thanks for read, and again, sorry for bad english.

No and once it ends you can't use it.

The coupon have validation for 5 days before caducated, and the purchase it's done, only less the pay of it. Here is the problem

If someone did the same to me and resides in Argentina, notice that I did for the purchase of platinum PagoFacil if you can pay over the next five days working days, although the daily reward of -75% is finished (my I finished the reward of -75% yesterday, and pay the coupon today, and got the same platinum).

What about the discounts where you select claim but not use. Where do they go????
