Just for your records: the crossgrade system does not work in my case. (I am an owner of Trailer Xpressions I).
Please let me tell you what I did step by step:
- I opened the product site ( I was logged in into my account)
- I scrolled down to "crossgrade" (lefthand you can see "intro price ending soon...")
- I clicked on "Crossgrade 149,99"
- the website shows an new pop-up picture telling me:
Are you a BOOM/Sonuscore customer? Already own the original Trailer Xpressions? You can crossgrade to get a $50 discount and bring the price down to just $149.99 by pressing the 'GET DISCOUNT' button below and entering your coupon Code in the coupon section.
- Ok, I click "get discount" and the price is showing 199,99 in the cart
- I go to my cart and update my cart - no discount although I am a "Trailer Expressions I" -owner
- but I am a "sonuscore" and a "Boom-libray"-owner , too. So I thought "how about using their codes..."
- SUCCESS: when I apply my coupon from "Sonuscore" I get the promised 50$ discount
