In my experience, for items not in stock, depending on availability, SAs can order for you either from their warehouse (takes a few days to arrive), online from H.com when you are physically in the store (you pay upfront and also the items arrive pretty quickly) or reserve from the stock they’ve ordered already from Paris (no telling when the items will arrive, but you don’t pay upfront and when the items do arrive the SA will be notified and will let you know).I’d like to know too. I went to see my SA beginning of Dec for a black GHW Kelly belt but no stock so she said she can order it in and I’ll get an email once it’s in store. I’m not sure if they request this via the estore or notify paris etc. I haven’t heard back from her so I was considering popping in as she may have forgot. She did say no payment required now once it arrives you pay
As to them ordering from H.com for you when you are physically in the store, whilst they do offer this, I have no idea whether this counts towards your spend/relationship with the store or not as you’re not buying from that store’s inventory, but others who know more may be able to advise.
