@ericjhonson,
As we all know that Black Friday brings exclusive deals and discounts on a vast range of products. So, there are chances that some retailers offer "not quite the same" products with extremely low pricing. These items are not duplicates but still hold low specifications than what you need. You can be careful while choosing the products from few categories such as electronics and furniture items. In some cases you will discover that to lower down the pricing, companies has chosen cheaper or low-quality parts to meet up the requirement.
Before giving your buy the last seal, do remember to check the specifications and avoid selecting the wrong product. Therefore, it totally depends on your choice, budget and the desire to buy at that moment. Make sure, before you buy anything online!
