Hi there, uber draco sets can only be sold for VD according to the BTA's rules. The value is changing approximately like 10/15$ for both of T2, T3 draco sets, it means to depend on how both the sides of trade are going deal.
BTA's rule is saying for your group,
Infinitian - Can trade via BTA anything that implies VD (Via Donation). You or your buyer/seller has to provide goods VD.
