Angel Konan has actually been pretty consistent in price from a low of 220 to a high of 260. First time she was available was at 233 which is actually lower than her current average. The ninja that has had a big drop in price is Shisui. Which started around 200 and has dropped now to 137 and has been around there for the last 3 months or so.

I see 8 ninja where their lowest price is more than 75% less than their average.

1) Kushina Uzumaki - 32/71 - 45%

2) Naruto Sage - 45/71 - 63%

3) Ay 3rd Raikage - 180/280 - 64%

4) Gaara 5th - 45/68 - 66%

5) Jiraya Sage - 40/60 - 67%

6) Tobitama Edo - 185/270 - 68%

7) Minato Jonin - 106/149 - 71%

8) Kisame Sharkmode - 167/235 - 71%
