People who love Nike know that its sneaker prices can be hard to digest. And for collectors especially, the limited availability of some sneaker styles can be even harder to stomach.

With Saturday's launch of Nike’s new Air Presto “Greedy” sneakers quickly approaching, sneakerheads are likely already strategizing as to where they will buy a pair for resale.

Even non-sneakerheads can appreciate Nike’s athletic and performance sneakers, which still fetch a pretty price when they hit the shelves. With that said, there's no shortage of websites and retailers that offer the sneakers on sale. Read on for a list of retailers and resellers to check out before you purchase your next pair of Nike sneakers. This website features a range of Nike footwear categories, from sport and training styles to retro basketball shoes. Sneakerhead also offers both women’s and men’s sneaker styles — some at 50 percent off and up. Nike Air Penny II kicks are currently available for $99.99, and a pair of Nike Flystepper 2K3 Premium Lifestyle sneakers are now available for $83.99.

Footlocker: The tried-and-true source for all things footwear, Footlocker has a decent selection of Nike trainers. Nike Kyrie 2 shoes are now available on the site for $99.99, while a variety of Nike Air Max styles are on sale in both men’s and women’s styles. This website is a great fail-safe for Nike kicks on sale — many of the prices are still the same as you would find them at other retailers like Footlocker, but it’s a good site to have on your radar if you’re looking for an assortment of Jordans and Air Max styles on sale. Plus, shipping is free.

Nike clearance: This is a no-brainer, but checking in with Nike’s sale items every so often is a good strategy to adopt — just in case you nab the perfect pair. Its lifestyle sneaker section currently features a range of discounted Air Jordans, including a cool pair of Air Jordan I Retro High sneakers.

Resale options: For resale buyers, websites like The Sneaker Authority, OSneaker, Kixclusive and Flight Club all offer an amazing assortment of collector-worthy pieces. While the prices are high, you’re guaranteed to find a pair you’re looking for, whether that’s a pair of Air Yeezy sneakers or Air Jordan 1 shoes.
