Frequently Asked Questions

What are promotional codes?

Promotional codes are alphanumeric phrases used at checkout to receive online digital discounts (or other benefits) when purchasing e-commerce products or services.
They are synonymous with terms like coupon codes, discount codes, voucher codes, and are sometimes called online digital coupons.
You can search for promotional codes from over 5,000 brands.
Additionally, the discountloom.com website features educational materials to learn more about coupons and get tips for smart shopping.

How can I get discounts and promotional codes for every purchase?

Finding coupons isn't always easy and can be time-consuming.
We recommend bookmarking discountloom.com.
If you're using a desktop device with Chrome or Edge, you can install it as a desktop app.
This allows you to quickly find the coupons you need and save significantly.

Are promotional codes useful?

Yes, but many offers are only valid for short periods. Retailers often run promotional code campaigns to boost shoppers' purchasing motivation, and many retailers use discount codes throughout the year.
In fact, our platform offers great discount codes from many brands, updated weekly!
