Amazon is working on a robot sewing unit that costs about as much as a $20 gift card, according to a report from the Wall Street Journal.

Amazon announced a $2.9 billion investment in the robotics startup last year, but the new company is still looking to make the machine available in a broader range of price points.

Walmart says it is testing the product in the U.S. and Australia, where Amazon has been offering its Alexa voice assistant as a service for the past two years.

The company is also testing the unit in a few Asian countries.

The robot unit is meant to be used for tasks that don’t require the use of a machine, such as wrapping towels or cleaning carpets, the WSJ reported.

The WSJ also said Amazon is testing a prototype of the unit at a local Walmart store in the United Kingdom, and it will likely roll out nationwide soon.
