we have a zen cart ecommerce website.
on the checkout screen (step 1 of 3), delivery information screen.
i would like to have a button there "forgetting something"
this button will list out all the products that they have purchased previously
but have not reordered on this order.
so, just incase customer is forgetting to order a product that they may be running low on, it will show it to them and hopefully they will order it relising that they ARE running low on it and have forgotten to order it.
it should show up as a list, just like they are ordering from a particular category,
but all the previously ordered products (not ordered on current order) must show up.
