I never had bought dual layer before because frankly the cost is still too high for me. I remember when the first burnable dvd-rs came out, I bought a 25 pack for $50. This was several years ago. By contrast, I bought a 100 pack a month or 2 ago for $25. I know dual layer discs have been out for a while, and they have come down in price, but they are still over $1 per disc. When is the price going to come down on these? I did buy a pack of 15 yesterday. Frys had them for $20. I was curious to try them out. Work well, but pricey.
