In fact, they weren't just cheap, they were free!

Mrs M's prescription pickup today was from a different Boots store to usual - after a trip to the regular Boots store on Euston Road, I was informed that the store was closing down and Mrs M had already been transferred over to the other Boots, so I had to venture deeper into St Pancras station. Once I found the second store it was simple enough to collect, and I was on my way to Mrs M to drop off her medication and pick up her shopping list and trolley.
