eBay is not going to let Amazon give all the deals away during Prime Day. To compete with Amazon’s mega-sale on July 15th and 16th, eBay has announced their Crash Sale. eBay is promising discounts of up to 80 percent on items from Apple, Samsung, Garmin, and others. The Crash Sale will wrap around several weeks of eBay having different sales on products. Not to be outdone, Target is challenging Amazon Prime Day with Deal Days. Target is offering “discounts on hundreds of thousands of items.” When do you buy more: During these sales or Black Friday?
