Thread: How to add a message to Shopping Cart page

I sell perishable items from my site, and during the summer months, this gets tricky because high temperatures will melt the products (chocolate). So, I would like to add a warning message recommending to the customer that he/she should upgrade the selected shipping method, and also would like to add the capability to purchase a "warm weather package", for an additional fee (I can like this to a separate product page). This message would be displayed if someone places items in their shopping cart, and then proceeds to checkout.

Can anyone recommend a way to do this without delving into custom code?

Not sure if this would be considered customer coding - but you could create an xml package named:

CartSummary.xml.config

if a package of this name exists it will be triggered when viewing the shopping cart. You could put your message in there.

Good idea. How does the package get invoked from the Shopping Cart page? Can anyone provide a clue?

Thanks!
