This Groupon deal is for a $20 Taste Station wine sampling card. Taste Stations are self-service automated sampling machines that hold up to a dozen wines and can be found in many of our Liquor Store locations. So to answer your question, you can sample wines anytime the Liquor Store is open. It is on your own time and is not a guided wine tasting. Taste Stations are a great way to try out new wines before you commit to making a purchase! You and your friend can visit the Liquor Store together to try out different wines. For more information and for a list of wines that can be sampled visit the taste station page on our website: http://www.nlliquor.com/stores/taste-stations
With regard to the limits, you can most certainly buy one for yourself and another for a friend.
If you have any more questions feel free to email me directly or give me a call!
