UPDATED OCT 17 2013:
Quill has made some changes to the program in the last six months:
Quill Cash now lasts 90 days instead of 60, making it possible to accumulate $80 at a time
To redeem Quill Cash you must have an order that totals $100 or more, AFTER all other coupons/discounts are applied.
I also discovered that Quill does offer some rebates here . None of the items are FAR or even close, really, but if it's something you needed to buy anyway, it can't hurt.
Pretty much everything else in the OP should still be accurate.
Lately I've been recycling ink cartridges with Quill and wanted to share some details of the program. Hope this will be helpful.
TL;DR version: Compared to the Staples/OD/OM programs, Quill is most useful if you actually want to buy office supplies (or something else Quill sells) and get a hefty discount and/or you don't live near any big box office supply stores. If you're looking to convert ink cartridges into rewards into cash or keep rewards rolling forever, you should probably pass.
Quill is an office supply retailer that operates entirely through delivery. They do not have any physical stores and take all their orders from catalogs and the internet. While they were acquired by Staples in 1998, the company still operates as an entirely separate division of Staples Inc. Interesting fact - Quill was the plaintiff in a 1992 Supreme Court case (Quill v. North Dakota) that confirmed the proposition that a company cannot be liable to collect sales tax in a state where it has no presence. Link
Quill also offers an ink recycling program. Since they have no stores to receive cartridge drop-offs, the program is conducted by mail. Quill provides free prepaid UPS shipping labels and/or boxes for you to ship ink cartridges back to them. Cartridges are rewarded with Quill Cash, which is Quill 's rewards program. Quill Cash can be used to purchase almost anything that Quill sells (it is specifically stated as "Not valid on HP and EPSON® products").

Here's how to do it:
Finally, I know some folks on here have a bad opinion of Quill due to their behavior on previous coupon promotions that got widely distributed and then were not honored. I can't speak to that but I will say that their terms and conditions are very clear that they do not have to honor a coupon that you got through unauthorized channels, and they seem to be stricter than most about enforcing that especially if there is a run on something. That said, I have had nothing but friendly, pleasant and helpful service from them and their customer service folks have gone out of the way to help me with various requests.
Please post any questions and I'll try to answer them, although I have put everything I can think of in this post.
