The advantage of Jim Beam and cola in can form is you can buy it in a 6 pack or in a 24can slab and take it with you without having to stuff around with mixing them, but I prefer buying the spirits and mixing it so I get the strengh I prefer. Obviously since the introduction of the 'alcopops' tax the price of RTDs have increased, and in my opinion buying the spirits is the more cost effective solution.
convenient to take to parties, bbq or to take to a friend's house
Quiet expensive when you can buy a bottle of 700ml bottle of Jim Beam and a bottle of cola and mix it yourself.
