Spotted this whilst doing my shop online. Cannot confirm if its instore as well, cannot even confirm if there are going to get delivered if ordered online, but its worth a try! My store is Taunton.
Please be aware, the worst thing that will happen is you won't receive anything and won't be charged. The alternative of course is that you will get them or a substitution which they price match against the item ordered!!!
If you're doing a shop anyway, and they are available in you're area, why not try? They might arrive.
