I'm testing the code on the website, I've added a couple of lines at the end of the blog posts. If you are a member and there is a download with the post it should tell you how long you have been a member. 

There should also be a code, like the' fdm' in the picture here. The codes are as follows.

fdm = Free Download for Members

nd = No download

fd = Free download

1/2atc = Half price add to cart

atc = Add to cart.

Please feel free to let me know if this works for you, or if it doesn't! It is only in the blog at the moment but I'll be adding it to the shop soon as well. Thanks for your help! Testing, testing 1, 1…
