Where do I even start with this store ?

Where do I even start with this store ?
I called the store to confirm that they have items I needed to build a computer, they confirm and say they had them. On their website, one item said it was 74.99. In store, the salesman tells me it s 109$. I tell him that his website and anywhere else in Montreal is 74.99, but I chose that store because it s conveniently located not to far from my house.
He looks at me and says what do you want me to tell you . Well my friend, I understand times are rough with this pandemic, but you just lost yourself a 300$ purchase minimum. As soon as I mentioned an apparently former store affiliation, they turn sour and say they got kicked out . Won t be seeing my money that s for sure.
