Ziterdes will be raising their prices as of September 1st, 2011.
From their announcement:
Place your order, stock up your shelves & storeroom and save money… because even if we managed in the past 3 years to provide you with stable prices, although we’ve had to include increasing commodity prices, today there is no way around for us to adjust the prices from September 1st, 2011 on.
All Orders (made by fax or email) which we will arrive here at our office prior to September 1st, will benefit from the old prices. Call orders can not be taken into account.
