the app has worked well for me over the past couple of years, customer service is very helpful, Surya S was especially great!

I have had this app "active" for 6 days...have sought support for several fundamental issues...major fail. The "add to cart" shows up no matter what configurations and options are introduced and the auction window is obscured on Shopify in standard Chrome desktop configuration. Then there is the warning of configuration "Need to (re-)configure Authorize.net details to make auto payment from auction winners" which pops up but there doesn't appear to be a direct method to resolve. I sent emails to 3 different webkul email support addresses 5 days ago and have had no reply. My "trial" of 7 days is about to expire and I have not gained any confidence in this app....
