I have plenty of Staples rewards to burn, mostly thanks to getting the free batteries each week, so I am going to take advantage of a pretty good deal they emailed me about early yesterday morning.  If you get the Staples emails, check your email for a HP ink deal – I don't think I can post the coupon, as the link has my email in it, so not sure it would work for you if you tried to print it, but I got a $10/50 purchase (in-store only), or $20/100 purchase (online or phone only), and in the same email it had an easy rebate offer to get a $10 Shell card when you spend $39 or more on HP ink, limit 2 rebates per mailing address.  I plan on printing 2 of the $10/50 qs and checking out twice to take advantage of the coupon twice and get 2 Shell cards – I only use HP ink, and can't find my model number anywhere but the office stores, so worth it for me.  I would do it online, but not sure how the rebate would work – Staples is close enough to me that I don't mind stopping in to make sure that I get the rebate each time.
