Just wondering why your website always shows “out of stock” for the BlueDuino, but I can clearly still order that product from aliexpress (from you)? I would be worried that many potential buyers are going first to your website, finding products that are out of stock, and then just leaving without thinking to check on aliexpress. Might be a better idea to just direct all purchases to aliexpress and stop showing “out of stock” on your site.
Just a suggestion.
