The Fifty Shades of Grey Stimulus Retailers have been quick to jump on the Fifty Shades bandwagon, sensing a rare opportunity to attract mainstream customers. Babeland, a sex toy retailer based in Seattle, has launched a mini-site “inspired by” Fifty Shades of Grey that suggests dozens of items, from a scented massage candle to a set of vibrating nipple clamps. Claire Cavanah, Babeland’s co-founder, says the books have breathed life into the moribund BDSM category, noting that sales of bondage gear jumped 375 percent in April. “Now we have an event called Fifty Shades of Hot Sex,” Cavanah says, offering practical demonstrations on spanking and bondage. “About 150 people have responded in the SoHo store [in Manhattan], maxing out capacity. We had to add another section to take overflow.”
