The couple did not disguise themselves, reports dailystar.co.uk. "We were shocked to see Robert and Kristen just walking around. They didn't do anything to disguise themselves," a fellow shopper said.
The couple, who went through a rough patch after Stewart cheated on Pattinson with director Rupert Sanders, bought a lot of things from the store.
"They just walked in, browsed the shelves and filled a basket with loads of goodies. They didn't seem to care if anyone spotted them. They bought a range of stuff including sexy costumes, DVDs, a pair of handcuffs and blindfolds," the shopper said.
