Crazy_THey @Crazy_T, in order to bring down the time it takes to solve payment issues with participants and place the final order with the vendor our system places hold transactions that should never clear but make sure that you have the funds in your account ahead of time. The goal with this system is to ship the products out faster.
As always, we will not collect funds from your account until the drop successfully ends.
If this doesn't sound like it matches what happened in your account, there is a 'contact support' button in your transactions page (at the top right of the screen). Reach out to them and they can tell you exactly what happened in your case.
