The countdown to Prime Day has begun, and with each passing day Amazon announces new Prime Day deals to tempt early shoppers. Today, we'll be looking at a number of Prime Day coupons that slash prices on everything from workout apparel to granola bars.

These Prime Day coupons are a somewhat hidden deal in that they do not appear front and center on Amazon's home page. In fact, you have to sign in to your Prime account to see the coupons and discounts. So, we've compiled a list of the best Prime Day coupons available right now. (Not a Prime member?
