That advertisement is for the Massdrop.com website which carry's some pretty awesome gear. Unfortunately they do not have a warehouse or proper shipping setup to Canada, so us Canucks would get dinged extra for shipping and customs which makes most of their group deals no longer worth it for us.
I still from time to time scour through their website checking out the various deals they carry though and I highly recommend checking them out even though I have not bought from them.
Everything from camping gear to P.C hardware and in between.
