This week has seen the return of limited time increased welcome bonuses on several cards from National Bank of Canada. The offer provides 20,000 bonus points and no annual fee in the first year when you spend $3,000 in the first three months on either the Platinum, World or World Elite Mastercard. With National Bank's A la carte rewards those 20,000 points are worth up to $200 towards travel and the first year annual fee savings ranges from $89 to $150 depending on which card you get. On top of this, if you get the World Elite Mastercard you can enjoy a refund of up to $250 per year on seat selection, airport parking and baggage fees.
