The Duchess of Cambridge has yet again shown that she’s just like us common folk, despite the fact that she will one day be a queen.

Kate, 37, was seen at her local supermarket with her two eldest kids, George, six and four-year-old Charlotte in tow on Thursday, where she reportedly snapped up some bargain Halloween buys.

Not only that, the savvy future monarch reportedly opted to forgo the checkout to scan her own purchases at the self-service counter.

The royal trio was spotted browsing the spooky wares at UK supermarket chain Sainsbury's in the Hardwick Industrial Estate, Norfolk, at around midday, leaving fellow shoppers stunned.

“Another shopper said that Kate was in the shop near the clothing and pointed where she was to me. I just couldn't believe it,” said Kathy Whittaker, 53.

“She was with Charlotte and George looking at Halloween outfits but her bodyguard was kind of watching people with phones and telling them no pictures,” she added.

Undeterred, Kathy managed to sneak a snap of the duchess as she paid for her items at the self-service check out.

Kate looked chic yet casual in a black polo neck and had her hair pulled back in a chignon for the shopping trip.

“I didn't see what she actually bought. The lady that told me she was there had children with her and she said Kate was asking her children what they were going to be for Halloween,” Kathy added.

“I think she bought some Halloween bits for her kids but I don't know what,” she said.

The Norwich local added that the duchess appeared “down to earth” and looked “beautiful as always”.

This particular Sainsbury’s store is located just 20 minutes from the Cambridge’s countryside retreat, Anmer Hall, and appears to confirm that the family of five have hunkered down there for the kids’ half-term school holidays.
