The shopping doesn’t stop for Princess Maha al-Sudairi of Saudi Arabia. Her Royal Highness caused a stir in Paris last year after she allegedly ran up bills totaling more than $15 million at 30 stores, including $75,000 at a lingerie shop. Now, Princess Maha, whose husband, Prince Nayef, is interior minister and second-in-line to the Saudi throne, is spreading her oil wealth in New York. She bought about $20,000 worth of glassware and silverware — in sets of up to 100 pieces — from the gift shop D. King Irwin on West 34th Street, where they’re still talking about it. The princess, accompanied by three bodyguards, tried to bargain with manager Jeffrey Dalgliesh to no avail, according to the buzz at Da Tommaso restaurant, and she paid by credit card.
