IMHO, that's an ok deal - but I still would get mine from Keg Connection! Even with a basic black plastic handle KC's are still cheaper by a few bucks taking into account NB's 10% off promo. Your difference may come down to shipping costs depending on what else your getting at the same time.
I haven't looked up the price, but have to add that Perlicks are great. Before I was getting stuck taps and excessive foam. I have had Perlicks for over a years now and never once have they stuck. Also they seem to pour a much better pint. I highly recommend.
Even with the discount and flat rate shipping, these are still more expensive than other places. Brewmasters Warehouse has them cheaper and you can get 10% if you have a coupon code, which are not hard to find. Plus $6.99 shipping.
P.S. I love Northern Brewer, but have to pass on this deal. Did not pass on the BTV 10% deal for my 10 gallon SS kettle though...woohoo!!!
