如果我没有理解错误的话,无论你是买家,还是卖家,物物兑换,还是钱物兑换,都算是一份交易。两者都有份参与。except finding one more opportunity to squeeze us dry for that few cents, i seriously cannot think of why transactions cannot be allowed over the gantry.
But, here is my question again, transaction is defined as the exchange of goods or services right? so if one party hands over some goods to the other party (one way traffic only), technically im not involved in any transaction right?
