If you’re a fan of all things retro, Grid’s framed disassembled gadgets are a celebration of vintage tech you will likely find charming. The company turns obsolete smartphones, gaming consoles, controllers, and other old-school gizmos into collage-like artwork placed in shadowbox-style frames, making for incredibly unusual pieces of home or office decor. And right now through September 12th, many of our favorite Grid items are up to around 40 percent off in honor of the company’s fourth anniversary.

A wide range of nostalgia-inducing gadgets are on sale; you can check them all out here. You can, for instance, buy the translucent Game Boy Color and the iPod Photo from 2004 for $159.20 when you use promo code GRID4 at checkout. For me, though, the most noteworthy deal is the iPhone 4S, which is down to an all-time low of $99 ($70 off). It was my first smartphone ever and will always hold a special place in my heart as a result — plus it’s also the first iPhone to support Siri. That said, if you want to go even further back in time, you can consider the first-generation iPhone 2G for $299 — a whopping $400 discount on the 2007 smartphone.
