Girl accidentally spends $733 at Sephora on her mum's credit card -- then gets even bigger surprise

A girl accidentally charged $733 to her mother's credit card and had a priceless reaction after realising what she had done.

Like everyone who does online shopping, the youth had her Sephora shopping cart filled with makeup that she wanted but could not afford on her own.

While entering an old gift card to check how much was on it, her transaction accidentally went through.

A Twitter video that has been circulating online shows her priceless reaction to the accident.

She then texted her mother to tell her about what happened, as well as tried contacting Customer Service to get a refund.

What was even more surprising was that her mother decided to give her the purchase for Christmas, causing netizens to marvel over the generosity.

What a lucky girl!
