How much is too much for a pair of flip flops? Forty bucks? Twenty? Ten? Chipkos , an L.A.-based footwear brand, thinks that $18,000 is a reasonable price to pay for shoes that barely cover your feet. In a recent collaboration with artist David Palmer, they’ve created a unique offer. Each pair sold will also get you 100,000 square feet of Costa Rican rainforest, an introduction to Palmer, a night at the LEED-certified Montage Hotel in Beverly Hills, and they’re even throwing in a complimentary piece of Palmer’s reclaimed wood and glass artwork. Ah, so now that you know your purchase will essentially be saving the rainforest, suddenly you feel like you’re getting quite a package.
