Which payment method you are using for cash out? For example BTC will not be paid out on the weekend.
With Payoneer or Skrill the cash out will be reiceved directly (under 5 min). We never waited longer than 30 min its perfect as seller!
The BTC payment will be paid daily from Monday till Friday daily between 11 am - 2 pm EST. But sometimes you must wait a little bit longer because of the confirmation of the BTC (except on public holidays BTC´s will be not paid out regulary).
All in all the payment on GF is really good if you compare it with other sides! Only on one point GF should be work. The BTC pay out rate is often to (extremly) high! We know it´s not directly the false from GF but the payout company should be changed in the future!
For high volume GC seller is it really unfair if you sell for example for 10K GC and at the payout you only get 8.5K. The other 1.5K which should normaly yours you lost because the rate isnt corecct. In this case you not only lost your earning you also must pay on it! At least you lost twice your money which is really unfair and mean 
For the future it would be really nice if they could fix this problem with the unrealistic BTC rate!
All in all Gameflip is the best place for buyer and seller for digital GC/Games/etc. We are safe and very thankful that the GF-Team works hard on it to make this place here so safe and very comfortable. For example if you have a problem on GF the support normally answering/helps you in under 72 h.
Its a really fast for a side with 4-5 million active users (on G*Y2a.com you can be happy if you will get your answer in under 3 month).
Thanks a lot for this guys
