Upsellio ‑ Discounted Upsells

Did exactly what I needed it to, and customisation options are extensive yet simple to use. Had a problem and messaged support, and was planning to go out for lunch while awaiting a reply because I know app support is usually slow, but I barely got out of my seat when the reply came in! Thanks guys for the great app and great support, I'll definitely recommend this to anyone who needs a solid upsell app.
