Item I bought went on sale the next day

Hi,

I bought a monitor friday on the canadian website for 429,00 CAD : https://www.dell.com/en-ca/shop/dell-34-curved-gaming-monitor-s3422dwg/apd/210-azep/monitors-monitor-accessories

The next day it went on sale at 400 CAD, so I wanted to change or cancel my order, but it was too late since my order was already "in production".

Is there a way to benefit from the reduced price without having to accept the delivery of the item and then make a return?

Thanks.
