Popup's on websites discount codes.

I went on to a website today and 2 popups came up, the first one was just a normal newsletter sign up but the second one was for a discount code, when you enter your email a wheel spins and it gives you your result such as 10% off total order, I noticed that one of the sections on the wheel was for a free product but seeing that its over 200 bucks I thought it was programmed just to come up with certain codes, I looked into the source code and found shoplify as the main operator for the shop but I couldn't find the pop with the free product nor any discount codes I landed on, is there a way I could find the discount code for the free product?.
Thanks
