No.

Buy the 30-day card that gives you 300 coupons then 50a day for 30 days. You can spend the rest on the spin wheel that gives 20, 30 or 50 coupons for 10 ingots or save them.

thx I planed to buy 500 ingots for 5days but thanks to your opinion I'll buy 500 for 4days and 300 1 days.

then i can purchase 300 packs and gold jonin medal.

I won't buy daily packs. thank you.

The most efficient way to spend your money in this game is on the monthly 300 ingots pack as well as Jonin medal. Anything else is overpriced so its up to you if you want to spend on it or not.

Yupz! As stated above, the monthly 300 ingots and Jonin Medal would be the best way to utilize ingots. Other ways that can help you is to make sure to recharge during a rebate and spend ingots during a rebate. Stacking the redeemable prizes you can earn on top of what you were actually looking to do or get is always the best option!
