Pricesaurus

Price drop alert app. Love it. Save it. Wait for it to drop. Paste a product URL. Pricesaurus watches the price. You get a mail or a push when it drops. iOS, Android, and web. Spanish and English.

We are not a store catalog and not a checkout. You already picked the product. We wait for the right price. Vexilo LLC builds Pricesaurus. Write alfonso@pricesaurus.com or use the contact form.

How it works

Copy a product link from any store and save it. Your list is ready for price tracking. Set an alert and get on with your day. When we detect a price drop, we let you know. Open the product from the alert and decide whether it is time to buy.

See how the price has changed since you saved the product. Compare recorded prices and make your decision with more context than a sale sticker.
