I had a look at today's Groupon deal for Montreal. It's for one month access to a fitness centre and 50% off the first spa treatment. I had a look at the spa treatments. I was boggled by the prices and the idea that someone would pay that much. Then I read it to my husband:
"Oxygen Facial To restore, rebalance and revitalize dull, dehydrated skin. Provides oxygen infused anti-oxidants to the skin.75min $150"
Notice something odd? "...oxygen infused anti-oxidants..."
That's as good as most over the counter cough syrups that have both a cough suppressant and an expectorant.
