After arriving at Mrs P's house to do some shopping for her, she asked if I could also post a letter for her and pick up a prescription. Thankfully, everything was fairly nearby so could squeeze it in in my lunch hour so zigged to Boots, zagged to the Post Office and then bolted back to the Co-op who had everything except small bottles of Buxton water.

I gambled on Co-op's small bottles of water being similar enough but when I got to Mrs P, she revealed she hates Co-op water. Quickly ran back to Co-op and swapped for two big bottles of Buxton and Mrs P was very grateful.
