O, how cool that you got a post purchase message. I think I might try and follow up with mine because it was all packed up while I paid I didn't actually get it in a box. I know it's big as it's a shopping bag however have seen other people have a box with them so a follow up would be good so I can ask.I agree, the SA I met at Sloane St was lovely. He messaged me after a few days to say thank you for the purchase! Harrods is a bit hit & miss - I met one that turned me away just because I don't have the code of the item I was looking for (I have a photo though). She didn't even check the system/stock room. I met 2 other SAs and they were ok. I am glad you found what you love!
I felt like in Harrods you had to know what you want, she went through a big list. It's like narrow down what you want so they can serve you and be on your way, when actually it's a big wad of cash you are about to drop!
