Good Staples Online Deal

Just used a $20 off $100 coupon to score CA Internet Security Suite (3-user) FAR, and added the Staples 8 sheet cross cut shredder for $49.00 before $30.00 rebate. Total cost with tax was $95.39. Total amount of rebates is $90.00. So for the tax cost alone ($5.40), I get a 3 user license of CA Internet Security Suite, and a Cross Cut Shredder. Good deal if you have a $20 off $100 coupon.

Is Ok if you really need the internet security or shredder otherwise even at $5 still the deal is not attactive.
