"mini" bottles of wine

[curious]

I saw at the local wine store some cartons of what looked like pop, but was mini bottles of wine, around 12-16 oz., I think.

It was 6 bottles in a little carton that could be carried, remined me of old days with bottles of coke cola (just aged myself, <BG> [img]http://www.wines.com/ubb2/wink.gif[/img] ).
Does anyone know anything about these? They looked just like the larger bottles, but were small versions, and I wondered if the companies had them as samples, for newbies to try out, or something.

Are they worth buying, or what? This inquiring mind wants to know.
Thanks all,

Janette
