Online retail giant Amazon has announced its new mini Echo ‘smart’ speaker called ‘Echo Dot,’ but the company has also made it difficult for customers to preorder the $90-priced device, probably because of supply chain reasons.

Amazon wants customers to preorder the Echo Dot ‘smart’ speakers using the Alexa voice-controlled digital assistant available in the original Amazon Echo wireless speaker and the newest Fire TV version.

However, for customers who do not possess either the Echo or the new Fire TV edition but are interested in placing preorders for the new Amazon Echo Dot ‘smart’ speaker, a loophole in the preordering process has been discovered by Localytics product manager Dwight Churchill.

The loophole – which will likely closed by Amazon any time – comprises a few simple steps. Customers who want to place Dot preorders first have to open the Amazon iOS shopping app, and Search for ‘Echo Dot.’ When the device shows up on the search result page, a right swipe on the device will add it to cart. The customers can then proceed to checkout.

Customers who preorder the Amazon Echo Dot ‘smart’ speaker this week will likely have the device shipped to them by around April 22, 2016.
