I can't post any links yet, but if you go to the staples website and search "fosa" you can find these for a heck of a lot cheaper than amazon. These are regularly $70 and $80 for the starter sets (you can check on amazon) and now they're on sales at staples!
I figured it was worth a mention, cheers!
No idea when the sale ends, but staples seems to have marked a few things down on their website and it's worth an investigation.
