Buying Dog food cheaper....

We've been using the Wolfsblut range (a DE brand) that we get from Petcenter.ch for about 4yrs now. Not the cheapest but keeps our Bobbery pack happy.

We also use Zooplus - and if you spend a certain modest amount (=1 to 2 bags), it really is free delivery, no surprise costs. And it gets delivered and left on your doorstep so you don't have to lug it home from the shops. It's a win-win (except for Coop and Migros).
