IKEA founder Ingvar Kamprad's frugal life revealed

IKEA founder Ingvar Kamprad flew economy class despite a $58.7 billion fortune.

Kamprad bought clothes at flea markets, reused tea bags, and took home free salt and pepper packets.

He avoided expensive haircuts, getting them during visits to developing countries.

His frugality was shaped by growing up in Småland, a rural Swedish province where thrift was a way of life.

Kamprad worked at IKEA until age 87 and died in 2018 at 91.
