Who may take money from people in one city and repay them with cheaper-priced Pairos they bought on their behalf in a different city?
No one; they are borrowing money and giving the lender their Tircha in transportation!
Everyone; perhaps this cheaper price will also come to the first city.
Donkey-drivers, for their reputation and/or business gains by doing this.
Donkey-drivers, for they are anyways going to the other city, so there is really no Tircha.
Everyone; for perhaps this person will one day become a donkey-driver; he too will benefit from the enhanced reputation which this business brings him.
Can a person pay a discounted fee to buy the still very-unripe grapes of a vineyard, that he will receive them when they are fully grown?
Never.
Always.
Only if the buyer brings his own oxen to work the land, for they may get hurt while they are working.
Machlokes between answers A and B.
Machlokes between answers B and C.
May one pay for wine several months before it is ready?
No. The buyer is allowing the seller to use his money for the interim, if he will make sure to give him only bottles of wine, and not vinegar.
Yes. It is part of the cost of doing business (a Mechila).
Yes. Even the good bottles of wine that he is given may still sour and turn to vinegar later.
Yes. The buyer wants wine, and never bought the bottle later found to be vinegar, even if he would have taken possession when he paid for it.
Yes, as long as the reason for this arrangement is not spoken out explicitly.
May a person pay other people’s property taxes and then harvest their fields?
Yes, always.
Only in a place where the king enacted this law.
No, never.
He may pay the taxes but only harvest up to fifty percent of the crops.
Every occasion requires specific permission from the king or his governor. Only then will it be permitted
When someone who was given money to buy wine at a good price did not, what must he do now?
He must always go to the special wine market and buy the wine now.
He must only go to the special wine market and buy the wine if he a certain wine wasn’t specified. If it was, he need not go, for we don’t know if they would agree to sell it to him.
In any event, he simply returns the money; he did not make a Kinyan to obligate himself to fulfill the mission.
