You must be a good fit for the user profile they used in their calcs then
I might be making this up but have a vague recollection* that these aren't discounted from the usual price but are a different saw with different specs that shares the same name?
*someone compared specs befor buying or bought another one 'cause it was a good deal and then discovered the differences? Google shopping certainly shows 2 different rage 3-s 210mm sliding mitre saws, Screwfix sell them at £170 and £100
