Brown's Need a Cake bakery, which employs eight staff in Reading, U.K., had to bring in temporary workers through an employment agency to fulfil the orders, at a cost of $19,500 (£12,500) — wiping out her profits for the year.
She also lost between $2.90 (£2.50) and $4.70 (£3) on each batch she sold, the BBC reported.
"Without doubt, it was my worst ever business decision," she told the BBC. "We had thousands of orders pouring in that really we hadn't expected to have. A much larger company would have difficulty coping."
Disclosure/Disclaimer: No position in any securities mentions, though, I do like cupcakes.
