Mike,
I'd welcome any improvement made to put a single specific item under the customers nose after a product is sold....NEW example (Water Lily Plant purchased....upsell product would be a bag of Water Lily Bloom Feed tablets...or how about our collector's Hosta 'Guacamole' associated with our copper id stake...for that matter, our pack of ten copper stakes could pull up a redirect to our permanent outdoor uv marker...a pack of tulip bulbs could redirect to our bulb planter) OK, thats enough new examples!
A redirect would take care of business as well as the sidebar idea, although I still like that concept also. The redirect would probably be an easier add for

. In fact, it seems to me that would be a rather easy add..although Im not a

programmer. I am confident that either of these ideas would help my sales..and thats always a good thing!
I guess I am behind whichever idea has the best chance of taking seed.

Bad pun.
