Benefield Spencer Glass Shop review for Preorder Now Presale Timesact

I used this app to set up a preorder facility on our shopify site, it was easy to install and easy to navigate. I had to get customer support help with adding the preorder badge on the product image. The customer support by email was very efficient and got my problem sorted straight away. I couldn't understand how to use the live chat feature, that didn't work for me but emailing customer support did .
