USA Rebates Starting Sunday? [CR1]

Update
I have been corrected, apparently all rebates start on Sundays.

thanks John

Joy to the money
Received an email today in which someone claimed  a retailer let them know the rebates would begin on Monday. Some kind of combo program.

i.e. Buy a 1Ds Mark III and 800 f/5.6L IS and receive $50

….. ok, hopefully better than that.

thanks james
