I want to increase the discount for each additional quantity

ハウスクリーニングのフォームを作成しています。

以下実現可能でしょうか。ご確認のほどよろしくお願いいたします。

I am creating a form for house cleaning.
Is the following possible?
Thank you for your confirmation.

①商品名に「エアコン」の文字列が入っている商品のいずれかの合計が２であれば-2000割引、３つだったら-4000円、４つは-6000円と数量が1つ増えるごとに-2000円割引額が増えるようにしたい。

I would like the discount amount to increase by -2000 yen for each additional quantity, so that if the total quantity of any product containing the string "air conditioner" in the product name is 2, then there will be a -2000 yen discount, if it is 3, then there will be a -4000 yen discount, if it is 4, then there will be a -6000 yen discount, and so on.

②商品名に「エアコン」の文字列が入っている商品を１つでも選択したとき

エアコンの機種名・型式をテキストでいれるか画像どちらか必須にしたい

I also want to prevent the quantity from being changed.

④商品で見積もり取ってから料金を決めたい。無料ではなくお見積りなど言葉を変更できるか

Hi contact821_contact,

Thanks for reaching out to Jotform Support. I'll need some time to look into this. I'll get back to you as soon as I can.

We appreciate your patience and understanding.

Hi contact821_contact,

You can enable the Special Pricing Per Quantity feature for each product. This way you can set up the price for each quantity selected by the users. Let me show you how to do this:

1. In Form Builder, click on the Push Cart icon of the Product List field.
2. Then, from the Products tab, click on the Pencil icon of each product.
3. Next, on the upper right side of the page, click on the Options tab, and then click on the Pencil icon of the Quantity selector.
4. Toggle Special Pricing Per Quantity to turn it on, and enter the price for each quantity.
5. Lastly, in the lower right corner of the page, click on Save Quantity.

Here's the result:

Unfortunately, there's no condition to prevent the quantity being changed. As for your other questions, I've moved them to new threads and will be helping you out here shortly:

• I want to require the other fields depending on the product selected
• Product List: Can I change the word free
• Allow users to select the desired reservation date and time

Let us know if you have any other questions.

Hi jotform support team
Thank you for letting me know how to solve the problem.
What I wanted to do was not only to have a discount when multiple items
were selected, but also to change the discount amount when the total
quantity of multiple items is changed.
Total quantity: 2
Discount amount: -2000
Total quantity: 3
Discount amount: -4000
Total quantity: 4
Discount amount: -6000

Hi contact821_contact,

If I understand you correctly, you want to apply discounts on the total amount. If so, then you need to create coupon codes. It's easy to add coupons for your products using the Coupons feature in Form Builder. Let me show you how to set that up:

1. Open your form in Form Builder and click on the Product List field.

2. Then, click on the Shopping Cart icon on the right side of the field.

3. In the menu on the left, click on the Coupons tab, and then click on Create Coupon.

4. Enter a Coupon Code and choose a Coupon Limit and set the amount or date to arrange the coupon's expiration.

5. In the next section, select a Discount Type and enter the Rate or Amount you want to use.

6. In the Apply Discount To section, select the Product option to apply your coupon to your selected products.

7. Then, in the Discounted Products section, select the products you want a discount for.

8. Now, just click on Save and that's it. You're done.

You can also apply a discount directly to the Subtotal or only Shipping. Let me show you how to do that: 

1. In the Apply Discount To section, select Shipping or Subtotal.

2. In the next section, enter a Minimum Subtotal Amount. 

Now, your customers can use your coupons to get a discount when they buy your products. Check out the screencast to see how it'll work:

You can check out this guide about How to Add a Coupon Code to Payment Forms for more information. If that’s not exactly what you’re looking for, can you explain a bit more so I can help you better?

Give it a try and let us know how it goes.
