They do home delivery. That is, my favourite supermarket, Delhaize (certainly not sodding Match), does home delivery. Or at least I thought they did. Until I read their website a little more carefully. What they actually do is allow you to go through the whole palava of ordering all your items online, where you then have to...go to the shop yourself and collect them. Brilliant. And they charge you €4.50 for the privilege.
Ooh, it's a long, tortuous process, as Belgium shuffles its way towards the demands of the twenty-first century. But, they'll get there. At some point.
