We have £180 in John Lewis Vouchers, what do we spend them on?

May I start with the closest John Lewis store is 2 hours 10 mins drive away in Cardiff. The only thing we really want is a Weber BBQ "Master-Touch E-5750" and they are selling them for £289, seems good, spend £110 on a decent BBQ. Get it delivered, feels like money well spent. But wait.... It's £20 to get the BBQ delivered. I look online to shop around and BBQ world are selling the same BBQ for £219 delivered next working day. So £90 saving, but can't spend the voucher. Would love advice on what you would do in our situation. Whether that's what to do about the BBQ, or suggestions for alternatives to buy from John Lewis thats actually worth the money. Also any similar stories of situations you might have lived through. We have recently bought our first house, it will be our forever house, we have a 3 week old baby. We are mid 30s, and don't want for anything except perhaps some big ticket items such as a new sofa or white goods. We have all the bedding, kitchen appliances, and crockery we need which are the only things that come to mind from such a store. Thanks UK in advance!
