Why...?
Free after Easy Rebate items (ream paper, photo paper, pencils, pens, labels, etc, cleaning supplies)
Free after Staples Rwards items
They also run 20% back in Rewards promotions every quarter or so (i.e., I spend $100, I get $20 back in Rewards)
My wife is a teacher, so that stuff comes in handy. Also, you can recycle ink at $2/cartridge. I'm a Staples Premier customer, so I can recycle 20 carts/month which works out to $40/month for little effort.
I simply go on eBay, buy a [Lot] of 400 cartridges for $60, then trade them in over the course of a year and half. I make money back on my initial outlay in two months of trade-ins.
I then use that $40/month to buy gift cards (Starbucks, restaurants, VISA gift cards, etc) from Staples.com -- you can't use Rewards to buy gift cards in-store for some reason -- or to put it towards technology items in the store.
Not to mention, that Staples has some pretty good clearance electronics deals if you monitor Slickdeals.net. Quick and easy money for resell on eBay.
You ask "Why", I say "Why not!" :biggrin:
