 Prime Day starts tomorrow, and as we hear from ABC's Alex Stone, the sales event started by Amazon could pull retailers in along its wake. Online sales on Tuesday and Wednesday will blow all records out of the water, according to a prediction from Adobe Analytics, which expects $14 billion to be spent online, not only at Amazon, but at all retailers that are going to be offering deals. Experts say there can be some pretty good deals, too. Categories like electronics, clothing, and cosmetics could see price cuts up to 22%.
