Thanks for the reply and advice!
Things turned out that I had no chance to visit H boutique in LHR airport because I didn't have time for it.
However, my flight was at 8ish PM, so in the daytime, I went to Harrods with my family and friend. Finally, I found the straps I wanted for my kelly watch! They have more to choose in this boutique! Since it was hard to choose from noir epsom and etoupe swift, they both looking good with gold hardware, I took both. When we saw the etoupe strap, my friend said she always wanted a bearn wallet in etoupe. We asked the SA if they have one in store. She checked with her iPhone. There was one in stock!! After waiting for 10 minutes, she came with an orange box, which was still sealed. It was a brand new bearn wallet in etoupe and silver hardware. It was so beautiful! My friend said she had hunted it for a long time. She was so excited. She never thought she could have one.
Then I asked for charms and rodeos. The SA said she only had pompom at this moment. Then I asked for the silver kelly lock charm necklace displayed in the store. The length was perect for me but I thought it would be great in gold, too. After checking in their system, she said they had other designs with diamonds. There was one constance charm with diamonds. She took it out from storehouse. It was so beautiful and well-made. It was really hard to take my eyes from it! However, it costed like 5700 pounds. Currently, I'd like to use this budget for bags, so I declined it. I should asked for bags at this time but I didn't have time for it because I had to do tax-refund in Harrods and went to the airport. Therefore, this was the end of my orange hunting story in London.
To sum up, among these boutiques in London, surprisingly, NBS had the least inventory for what I was looking for. Maybe, that was because I visited in the afternoon and they had more customers than other stores. Things sold quickly. If you are looking for jewelry, wallets and accessories, I would recommend Harrods. They have abundant inventory. They also had more bags displayed in store. Though they were not what I was looking for.
In the leather department in NBS boutique, there was almost nothing on it. SAs were all very nice in these boutiques!
I met an arrogant SA in NBS Chanel... Except SAs in Paris, other Chanel SAs in Okinawa, Macau, my city- Kaohsiung I met were all quite arrogant. This is why I love Hermes because most SAs are nice and friendly.
Thanks for taking time to read my story. I hope I will have something to share with you soon.
Maybe I will posted some revealing photos on the thread, "What is your last Hermes purchase?"
