anbu clothing? or you mean fukokumaru clothing? fuko could be around 4K coupons...and i think it would give straight power up..if you have a grand team planned with hanzo you can go for it...even fuko,, i think if you wait you will get at good price in lucky board later on if it follows the anbu clothing trajectory...

If you are talking about anbu clothing, its available in treasure tof the sage, but the best price with max discount is 5250 coupons for 50 frags, which is costly compared to last time it came in lucky board around 3.8k
