Normally I am a bit 'meh just keep it' about these things, and 'most people would keep it, blah blah blah...' But that's if it's a £1.39 block of cheese, or a book that cost three quid.
I have had occasions where I thought an item wasn't coming - and it has gone past the 'should have been delivered by' date, and I have been reimbursed. Then the item has turned up. When I phoned them/emailed them to say I got it, they told me to keep it as it wasn't worth their time and effort and money to have it back. These have always been items that cost less than a tenner though.
£175 item however? That's a whole new kettle of fish. I would say I had received it yes, and would offer them the money back.

You're obviously not doing this to be devious but my ex-husband would do things like this intentionally all the time and then a few weeks later, there would be an obscure expense so actually he was never better off. I used to tell him it was karma restoring balance.
I believe in this too, and it does happen.
I know someone who kept a purse she found, that had £350 cash in it, (2-3 years ago,) and she knew who it belonged to as it had the woman's driving licence in it, with her name and address on it. She kept the money, and spent it on frivolous crap.
3 weeks later, she got a huge repair bill for her car that she was NOT expecting - £475.
Karma biting?
Perhaps the car repair MAY have happened anyway.
Maybe not.
