£30-ishK and up. Plenty of tourists do that, and it's more impressive if it's a single piece like on a watch, jewellery or double-faced or cashmere blanket/rare wood box or a leather outfit. Last in CP I saw someone pick-up a lamp they ordered and it was an astronomical amount.
Nothing wrong with anything H sells, but let's face it, umpteen Rodeo charms, C and O sandals, multiple twillys, Constance belt kits and clic-clacs etc are not going to buy brownie points in a shopping destination tourist area, however much they add-up to, they are basically Hermes pick 'n' mix add-ons. Harrods sells one-off gold/diamond pieces like they're sweeties.
Think logistically: The wishlist is to make sure that what comes in goes out ASAP. 2, 000 CP customers in front of you will have K/B 25 ghw on their list so chances are low, a 'bleu something' Geta means you're prob only up against 12 others.
I would never have said this 10 or even 5 years ago, but if people don't want the whole H lifestyle they are far better going to a reseller or trying Paris.
