I find THREADFLIP to be one of the worse online consignment apps out there. First, half of the time I've had issues with there tracking system. I ship, and it doesn't update. I have to email which can take up to 72 hours to receive a reply. Then payments have not been released in a timely fashion but they have there 20 percent COMISSION for doing nothing. Latest is 3 days to transfer proceeds to PayPal and I still have not received my money. Tradesy by far has the best customer service and actually responds to their buyers. Poshmark is my second favorite as my payments have always been timely and buyer pays shipping and not deducted from proceeds like THREADFLIP does. After I receive my funds, I'm done with this horrible app forever.
