I am looking for an add-on that will do all three. I need it to work as pop-ups which then takes the yes, no, selection and adds it to the cart. Let me define all three for this purpose:
An Upsell is a related item that costs the customer more and will replace the item they choose
A cross-sell is a related item that will be ADDED to the order
A daily special is an item from the specials list and would pop up at checkout time
I am not interested in mindless talk about add-ons that fill one or two requirements brought on by people who love their voices and thing every word they utter is historic and monumental (yes, I did actually point a finger of guilt at that breed of poster who ultimately annoys the masses). I am only interested in free or paid solutions that do ALL three and do them well. Editorial comments can be painted on your neighborhood walls.
Want an example of how it works? Try harryanddavid.com and see that big click-and-order businesses are big for a reason. Are they the only programmers who can make that happen?
