How to show drinks container deposit

Hello,

I'm not sure if I'm on the right thread for this but I'm wondering if anybody can help, I want to sell craft beer cans online through my e-commerce site, I need to add the deposit Return Scheme Tax to the cans I sell, it's something we have in Ireland now, it's 0.15c per can, is there a way this can be calculated at the checkout on specific products or do I just have to include it the price?

So if the can is €3.50 +0.15 Deposit scheme Fee it will be sold at €3.65 or can I show the breakdown of the charge on the checkout page? 

€3.50
+0.15
€3.65

Ive attached a screenshot of how it looks on another website just for reference

Any help would be greatly appreciated

Pip

Thanks for the reply @paul2009, yes that's the Re-turn scheme, I'll work with it as a full-price option instead.👍
