There are many food products that naturally fluctuate in size from piece to piece.
For example: Pork roasts will generally vary in size; at a grocery store each pork roast will be priced slightly different based on the exact weight of each roast.
FreshSpoke has created a price adjustment system to deal with products like this. In the product profile, sellers let us know the average price and the weight fluctuation range of their products. Using these figures each product is given a price range:
As it clearly states in red text below the price box, buyers will be charges the maximum price for each of these products and then credited once the seller confirms the actual weight of the available product. Buyers will be sent a notification once the seller confirms the final weight. Find out about price adjustment credits here.
