The Botanic Garden Shop - do read the receipt for in store exchanges and refunds! They will be followed to the letter with little empathy for the customer.
I have previously bought from the various Cambridge University Curating Cambridge shops, both online and in store and have been entirely satisfied. My recent lack luster experience was at the Botanic Garden Shop today. The returns policy seems to vary so be sure to read the receipt blurb. I had a gift receipt and the item was faulty so I wasn't able to try the gloves on. I returned the item and chose to swap it for another pair, although at this stage as they were faulty I could have opted for a refund. Once home I discovered when I tried the alternative pair, that the fit wasn't good and the fingers too short for me. I took them back to the shop to discover that all sizes were a poor fit for me. I therefore requested a refund and was told that I could only have an exchange as the goods weren't faulty. When I queried this (as the original ones had been faulty) I was told it wasn't possible as (correctly) I had swapped them and that the 'system' wouldn't allow for refunds on non faulty goods. I ended up buying some plants instead as no credit notes were available. I said how unhappy I was about the situation. It seemed that the disjointed system took precedence over any customer service or satisfaction.
