Query: upset

When making the purchase I was unaware that there was both a double disc and a single disc version of this product. When i researched it I only found the double version. I thought I was buying the double version and did not see any disclaimer that there are different versions and I needed to check which one I was buying. Had I known this was a single disc version, knowing only about a double disc version being available I would not have made the purchase.
