Shops who don't know a thing about what they sell

I was out shopping with SWMBO today and we venteured into Harris Scarf(for those of you not in SA its a bit like Myer/Grace Bros) I spotted 3 Waeco 110lt fridge bags leaning up against the end of an aisle in the camping section. As i know a couple of people who have this fridge i thought i would find the price out to tell them. After searching for a few minutes i came to the decision i would ask a fellow to scan it for me at the camping service desk. Not known it came up. So he rang this person and then that person then the manager who suggested they ring other stores to see if they knew. In the end i got sick of waiting and left my mobile number with him to get back to me. He called a while later saying sorry but no price anywhere could be found. Unbelievable!!!! I am expecting a call back tomorrow from someone high and mighty who will give me a price lol. If its a steal of a price i will post tomorrow and let any owners know where to get a cheap cover.
