It used to be that buying stuff in the market was cheaper than shopping in stores but that seems to have changed with low price supermarkets like Lidl and Aldi - except today.
I ran into Barcelona's famous Boqueria market and selected a kilo of fresh tuna for 15€, some green beans for 3€, a pair of ace kitchen scissors for 12€, a tin of new improved Ghana Fresh Palm Nut Cream Concentrate for another few euros and finally got a right short haircut for 4€ (plus a 1€ tip). Bargains the lot :-)
My barber was so pleased with the tip that he agreed to come out and be photographed in front of his shop.
