I usually purchase most of my DVDs from Amazon, but I use Deep Discount DVD for box sets because they tend to be cheaper. Last year I bought Homicide: Life on the Street (HLOTS), Season 3 from DDD and had a defective disc in the set. I sent the set back and DDD replaced it without a hassle. Earlier this year, I purchased HLOTS, Season 4 from DDD and have now discovered a defective disc in this set as well. Now I'm wondering if DDD stocks defective merchandise (which is why their prices are low), or if the quality control on the HLOTS DVDs is just not very good. Has anyone else noticed a trend of defective discs from Deep Discount?
