Just taking a stab at this.

Use gift wrapping at checkout, change the labels from Gift Wrapping to Cold Pack and charge $2. But the user must click on it, or remember to click on it.


Or in your prices, find all chocolate products and add $2 and state somewhere on the site that a cold pack is included.


Or create a product option for all chocolate product. On the product details page allow the user to add a cold pack for $2 and hope they remember to do so for each package or product that required cold pack.
- Actually make it a default option to have a cold pack for your chocolate product in the summer, and then change the default option to null/none cold pack.
