The flash sale will kick off tomorrow, July 31, and run through Thursday, August 9, available on Sprint's website and through over-the-phone orders. Sprint's announcement also follows the reveal of its new "Unlimited Plus" and "Unlimited Basic" smartphone plans earlier in the month.

"Sprint’s Flash Sale is delivering a fast, simple and convenient online shopping experience, something we know consumers crave," said Dow Draper, Sprint chief commercial officer. "This is the first time Sprint has offered iPhone 8 at the unbelievably low price of only $8 a month with Sprint Flex. Now is the perfect time to become a customer because Sprint has the network built for unlimited at the best price. Don’t wait; iPhone 8 for $8 a month will only be available until Aug. 9."

There are a few other deals going on today, starting off with savings on App Store and iTunes gift cards exclusively for Costco members. Those with a member account can get the $100 iTunes e-gift card for $84.49 and the $25 iTunes e-gift card for $21.49, coming just under the usual 15 percent discounts the cards see at other retailers.

On eBay, customers have the chance to save 10 percent on back-to-school shopping with the company's latest coupon. This one isn't a sitewide code, but instead focuses on items including backpacks, laptops, cameras, dorm essentials, and more sold by select sellers (you can find the full list at the bottom of this landing page). Once you find eligible items worth $25 or more, enter the code PUMPED10 at checkout to get 10 percent off your order through 11:59 p.m. PT on August 3.

At Rakuten, third-party seller BuyDig has again discounted the Beats Studio3 Wireless Headphones (Black) to their all-time-low price of $181.90 with code BYD37, down from $219.00 and coming about $50 under the current $240 price tag at Walmart and Amazon. Rakuten has also kicked off a new 15 percent off sitewide sale, giving customers the chance to save on a variety of products using promo code SAVE15.

Another notable sale this week is Nike's 20 percent off promo code HOT20, which you can apply to Apple Watch and band accessories found on this page. With this sale, the most expensive Aluminum Apple Watch Series 3 model (GPS + Cellular, 42mm) is marked down to $343.20, down from $429.99.
