Funnily enough, I've been looking at these on Amazon recently for a friend's birthday! The cheapest you can get them on Amazon is £4 (as an add on item only, minimum spend £20), or £7.99 each with £3.99 postage!! Haven't tried them yet so can't comment on taste, and you have to add your own alcohol, but a good price compared to anywhere else and a nice easy cocktail for parties! Each makes 4 cocktails. Flavours available - skinny mojito, strawberry daiquiri and passion fruit martini.
