Preeti Aroon for FP

At the Claude Taylor Photography Gallery, just a short stroll from FP's office at Dupont Circle in Washington, you don't need dollars if you want to buy a print. Just hand over your euros -- each gets you $1.50, according to this sign in the window. The studio began accepting euros in March, owner Claude Taylor told the Washington Post, citing his perception of increased numbers of European tourists due to the weak dollar. The phenomenon isn't limited to Washington. Some stores in New York have also been accepting euros.

Meanwhile, also in the Washington area, guess who's buying SUVs in this era of record-high oil prices? Europeans. With the weak dollar, they can import jumbo vehicles at teeny prices.
