Excellent tips - I'll add this one for US residents as well - Harrods online will deduct the VAT from the price of the bag if being shipped to the US. That is sometimes a steeper discount than MW (sometimes not) and they have a broader selection of Mulberry.I'm an English girl living in the U.S, phone the NYC Madison store and you avoid the sales tax, or if you order from my wardrobe they deduct around 20% as you're not a U.K resident. That's how I got my patent bays for $995 instead of $1200
Nordstrom in San Fran stock Mulberry and so do some of the East Coast Nordies. They're not listed online and I've managed to get one in the pre-select before.
