The actress and fashion designer - who, alongside her identical twin sister Mary-Kate, was recently ranked as the 11th richest woman in entertainment with a combined wealth of $100 million - was spotted trying to unsuccessfully get a deal when purchasing some flowers in Hollywood.
An onlooker explained to National Enquirer magazine: "She was checking out flowers at Moe`s Flowers in West Hollywood which were on sale for $12 for 10 plants. But that wasn`t enough for Ashley, who had the nerve to ask, `Can I have these for a dollar each?`
"After being told, `Sorry, there`s no haggling here`. She replied, `But they`re not the finest quality`, while plucking off dead leaves. The guy then insisted Ashley either pay full price or forget it so she coughed up the 12 bucks."
It could be that the 24-year-old star is saving up for a designer handbag, as she recently admitted she can`t wait to get her hands on a Crocodile Birkin bag made by French luxury group Hermes.
She said: "The next one I want to get is the crocodile Birkin, but that won`t be for a while. Crocodile is my favourite!"
