Sorry
I am perfectly able to go into a store with far more money that the cost of the item I seek to purchase; and not spend any of the extra money.
I make a list of what I want to buy before shopping and do not add impulse items to my cart.
Buying secondhand is not the answer to everything. I don�t want clothing or bedding used or worn by others, same with upholstered furniture. Not taking a chance on what might be inside to make me sick.
I prefer a full manufacturer�s warranty on automobiles, and high end appliances, HVAC equipment, etc.
No difference in a new versus used diamonds and I buy used serforim regularly.
It�s about buying what you can afford comfortable while meeting all you obligations such as maaser.
