Hi there. I'm wondering if it's possible to bypass the /subscription/packageDetail.aspx?pkg=xxxx page and add a subscription pack (or a few) into the cart directly by entering that information into a URL. I know it's possible to apply promo codes, populate a contribution amount, etc. this way. Has anyone ever done this successfully?
If it's not present in the documentation (and I don't think it is) then this is not possible without extra code. This could be accomplished through the use of a precart.aspx customization -- your link would point to a special set of arguments for that page, and the customization would modify the session to add the desired product to the cart before redirecting to whatever you want to use as a landing page.
