Giving chomesh on maeser of dmai and how we know there’s no onah on karka

Many halachos in regards to chomesh of pidyon hekdesh and maeser sheni

How your Podeh less then a perutah of maeser sheni and maeser sheni that went out of the chomos why they are batul brov

Onaha on coins,small towns and onaha and Midas chasidus to take back up to 12 months

How we know onaha both for the buyer and seller,what does it mean there’s no onaha for the tagar, and noseh vnosen bamana

Less then and more then a shtus according to the rabanan when is the mechila and onah for a non merchant

Going back on one’s words and where do we say onah is it only on value or even sale price

Machlokes maos konos Mdoraisa,machlokes if mi shapara is a curse or notification,and is mi shapara on the rest more then a down payment

If somebody buys something with a sack of cash, who provides the suddar for chalippin,can you use peiri for chalipin, and is maos konos min hatorah

Can you be koneh money with chalipin and lahalacha can you use money for chalipin
