HP Ink Cartridge Rebate

I needed to buy ink for my HP printer/scanner/copier, particularly since I have Staples ink coupons handy. After a little searching, I also found a $10 rebate on double packs of HP ink. Here is the ink rebate if you need it.

Total cost:
$26.99 for 2 cartridges
-$9.00 ink coupons (3)
+.76 tax
$18.75
- .52 that I'll get back from shopping through Ebates
-$10.00 rebate
$8.23 for two black ink cartridges, or $4.12 each. Not bad!
