We should never ever show interest on products, Willingness should be there to bargain on big bucks, don’t ever accept on big bucks, Try to negotiate and work on the price to make our bucks valuable.
If the shopkeeper knows that we are highly interested on product he will never decrease the price , Deeside on the fair price and start to bargain.
If you’re not okay with the price be willing to walk away from the place. Try to compare the price with the other shop and other brand and make them to feel that they have cons on their products.
Don’t ever say the pros of the product.
Don’t ask for the discount where that can’t be done from lower level try to negotiate as much as you can and make the payment.
