Is this rule new? It' let me put 4 BMO vouchers in the cart, but rejected at the last step. If there had been enough DM for a $500 voucher I guess that would have been accepted, but there was only enough for $400

.
*Please note there is currently a maximum of 2 certificates per calendar quarter on this item.
[edit: very last step:
Bank of Montreal $100 Investment Voucher exceeds the quantity limit of 2 for the period of 01-Jul-2015 to 30-Sep-2015. Please remove item from cart
I'm guessing when they say "discontinued permanently on Oct 1" they mean 12:01am and not 11:59pm.
