I have sold to them before and use there pre paid label and got my check in about 2 weeks, because I am not able to track or add insurance to there pre- paid label I pay to ship.I think they can track it when you use there pre paid label.hello everyone! i just shipped out 4 bags to sell to avelle. I used their provided label, but now after reading reviews im kinda freaking out because i was unable to add tracking and insurance since the label was already pre-paid. i did email them that i shipped. has anyone have had positive feedback with selling to avelle?
