Limit order by Alcohol volume, 10 liters

[Lombok Design S.L.]

Hi everyone,

 

I'm developing a new ecommerce website for France. It's something like an alcohol mart (sells alcohol but it sells other things like deodorants, perfumes...).

 

The problem is that in France you can only buy 10 liters of alcohol per order. I have been thinking about a solution and I think that the best option is to do it with Characteristics (Product > Functionalities > Characteristics), create a new characteristic called Volume (in milliliters) and limit the order when the sum is over 10 liters. 

 

Do you know about any module that can work? Or any other solution?

 

I'll appreciate your help a lot. Any kind of advice is welcome.

 

Thanks!
