For the OP, Never do past 300 for a refund at this point. The motivation behind why I state this is on the grounds that dependent on math, its never a decent arrangement to go to the 500 or 800 space. You could rather complete 3 full 300 discounts with a similar measure of parchments. You will get an additional 198 seal looks from those 3 refunds (66 seal scolls per discount). That is 200 more seal scroll pull advance. When you consider it in numbers, Lucky Patcher 9Apps VidMate the 800 achievement is simply unadulterated garbo.
