・it is a good deal・it is a good buy
「划算」在英語可以用 it is a good deal 或 it is a good buy 等來表達。
You can earn points for utility bills, so to pay with a credit card is a better deal.
（因為支付公共事業費用可以累積點數，所以用信用卡支付更划算。）
This set is half the regular price, so it's a good buy.
※utility bills（公共事業費用）
This set is half the regular price, so it's a good buy.
（這個組合套裝的價格是正常價格的一半，所以非常划算。）
