I was shopping for some cookbooks for my dad for Father Day and came across this seller who is offering an additional 10% off books at the checkout on Amazon.ca, All of the orders are also eligible for Prime.
Thought it was worth a look/post if you're in the market for a new book/cookbook
I am a new poster so I can post links to the site, but if you search Garde Manger Hardcover - Apr 24, 2012 by Chuck Hughes (The book I got my dad) - The Seller is Strikezone Deals and an additional 10% is taken off at checkout.
