All Staples stores now accept Amazon returns, without the need to box up the items. As with similar partnerships with Kohl’s, Whole Foods, and UPS locations, you’ll generate a barcode within the online return system which they’ll scan at the Staples store and process the return.
From what I’ve been told by Amazon reps these barcode returns are not interchangeable, and you need to generate the proper scanning bar for each location.
