I order Sharp's, which is made by the Miller Brewing Company. I like it better than O'Douls, and I'm not sure if they have any other brands of n/a beer other than Sharps.
My DW has also ordered the virgin drinks, she likes them.
The cost for Sharp's is the same as a regular beer, about $3.50, and it comes in the can. I think the cost for the virgin drinks is the same as the regular version too, although I don't remember exactly.
We also had the sparkling cider instead of champagne, not sure of the cost though because it was a gift.
