Ah, Prime Day. What started as a 24-hour flash sale for members of Amazon Prime in 2015 (during which 24,000 Instant Pots were sold) has evolved into a multi-day extravaganza that’s effectively forced every online retailer to host their own mid-summer sales.Amazon Prime Day now lasts a full four days (not to mention the early deals drops that Amazon’s been doing), from Tuesday, June 23 to Friday, June 26.It’s not only for buying big-ticket items on sale. You can find lots of deals under $50 (and even lower), and it’s prime time to stock-up on boring basics, too. (But if you’ve had your eye on something bigger, there are always discounts on Apple products and other tech.)And Amazon isn’t the only place where you can nab great bargains during this time.
