Hi
We can't link to competitors so you would have to use your google skills. A Gigabyte Z390 Aorus board would be a better option anyway if going with an Intel build.
i.e
My basket at Overclockers UK:
If it has gone back up in price on here then not really much you can do. You could try asking in the customer service section to see if they would sell it at the lower price.
I would take the Gigabyte though as it has the better VRM. If you don't need wifi, the standard Aorus Pro is £179.99.
