It's clear at the fine print that it will not include tax at time you purchase from Groupon!
The IRS states the sales tax has to be charge at full amont of the transaction, We (Brazil Brasileiro) are giving the discount on the total sales but the IRS not!
we are folowing rules and regulation impose from our goverment...fill free to contact the IRS yourself and clarify you question.
As far as gratuity if your table has more than 6 peaple "yes" a 18% gratuity will be add at you final bill like every other place!
Hope we are clear and you dont fell "fooled"...and please fell free to move down the road!
