We had anticipated this desire when we designed Upsell Express, however, we also have some planned changes to Bundle Offers as well.
The changes that are slated for Bundle Offers will ultimately allow you to use a bundle in Upsell Express.dustin commented
Hi Guys It would be great if you can set it up so we can attach Up Sells to bundles. Right now I have my up sell as a default so I can have it work with bundles. It is only a short term solution because if I ever need to sell a single product that I don't want Up Sells attached to it is going to really create a headache.
How will we be notified once you have this up and running?
