# How can I decrease the price using the same number used to increase?

I’m trying to decrease the price when the user presses the minus icon using the initial price, but then the new price after increasing is the initial price

```quantityHandler: function (action, product) {
// Increase or decrease quantity of product
try {
const newItems = [...this.products]; // clone the array
let idx = newItems.indexOf(product);
let currentQty = newItems[idx].productQuantity;
let price = newItems[idx].unitPrice;

if (action == "more") {
newItems[idx].productQuantity = currentQty + 1;
newItems[idx].unitPrice = price + price;
} else if (action == "less") {
newItems[idx].productQuantity = currentQty > 1 ? currentQty - 1 : 1;
// Decrease current price using the initial price
}

this.products = newItems; // set new state
console.log(this.products);
} catch (error) {
}
},
```

```quantityHandler: function (action, product) {
// Increase or decrease quantity of product
try {
const newItems = [...this.products]; // clone the array
let idx = newItems.findIndex((item) => { //compare with some unique identifier
return item.id === product.id
})
let currentQty = newItems[idx].productQuantity;
let price = newItems[idx].unitPrice;
let perQtyPrice = price / currentQty  //per unit price
if (action == "more") {
newItems[idx].unitPrice += perQtyPrice;
newItems[idx].productQuantity = currentQty + 1;
} else if (action == "less") {
if(currentQty > 1) {
newItems[idx].unitPrice -= perQtyPrice;
newItems[idx].productQuantity = currentQty > 1 ? currentQty - 1 : 1;
}
}

this.products = newItems; // set new state
console.log(this.products);
} catch (error) {
