Buy One Get One Free promotion

[lillebike]

Be able to do a BOGOF (Buy One Get One Free) promotion `
I want restaurant to be able make promotion on specific products that would look like : buy one, get the second for free
it needs to be on specific products (usefull for fresh product that are gonna go off soon)

I want
thi kind of promotions to be added to the promotion options

Whereas currently this happens
it's not there :(

It also means that if the clients buy 3 they get 3 for the price of 2, it needs to work by pairs (I guess you see what i mean all supermarkets do this)
