If anyone's looking for a cheap bike lock, found this in B and M Kilmarnock today, marked at £2.99,originally £5.99, going through till at £1. They had about six on a stand with other bike stuff past the tills.
Before I get slated about the quality of these locks, it's only £1, and it should be fine if you're just nipping into a shop.
My husband had a £40 D lock picked, so if someone wants your bike, locks are a minor barrier.
Cashier said it would be national, as the tills have been changed.
