First to answer get brainliest when

what were drawbacks of voluntary trade during india's vedic age?

(i need examples, i have some already written out, i just need 2 maybe 3 examples.)

1) traders might be attacked by other civilizations and looters
2) They may disagree upon the pricing and the worth of traded items
3) One may want to get rid of a item, another may not want to buy it, resulting in hatred and eventually war if it becomes too 'aggressive' 

hope this helps

The nickname would be : " robber bandits" i believe
