Congrats!
All high paying offers from ALL offerwalls are credited in 30-60 days. However, they do count towards the Daily Checklist bonus immediately.
Same goes for some red flagged surveys from Sampilicio.us
Go to the Offers-History page and you will see the Pending offer listed in orange with an exclamation mark.
Hover your mouse over the exclamation mark and it will tell you when the offer will be credited.
