Went to Halfords to get a replacement inner tube for my Boardman MX bike. The only one close to the size I needed was the Continental brand priced at £6.99. About to walk to the till with one when I glimpsed several of these Boardman branded inner tubes which were the correct size but had no price labeled. They rang up on the till at £1 so I purchased several. Seemed like a good deal to me.
