I got my bottle of 1818 for the same price during their last sale. It's a HUGE bottle and it is absolutely one of my favorite scents. Great staying power and it just REEKS (pardon the pun) of class.
Just for comparison's sake. Just before I bought my bottle (this last summer) a gent on E-Bay was selling a bottle as "discontinuted) for $89.00. When I e-mailed him that it wasn't discontinued and what the price currently was, he asked for the "source of my information." I e-mailed him the link right to the Brooks Brothers' site.
