The Canon Direct Store has the super-small and super-light Canon EOS Rebel SL1 brand new for $424.99. Start checkout to see this price. This is the absolute cheapest we’ve seen from an authorized dealer for this body-only.
This smells like a price mistake — there are two simultaneous “Instant Savings”, one is $100 and the other is $50. Compare with $549 new at other authorized dealers — this is $125 cheaper.
