I think SS needs one central "cookbook" on all varieties of suggestive selling. Cookbook should show full code and examples of real sites using these techniques. Lots of bits and pieces are scattered around this forum and elsewhere. Many terms. Confusing too about cross sell in the cart and on more info pages.
Appreciate Lauren's taking time to post this full cross-sell code and instructions for implementing it:

We have cross sell working in our cart and are just now thinking how to sell related products on more-info pages using Subproducts. Goal is to show related shirts with all pants, and vice versa, on our clothing site.
I feel really dumb about this subject until I look at many other SS sites that should be doing more suggestive selling and aren't.
