ComboInk has a new October promotion through 10/31:  $5 off orders of $55 or more with FREE shipping with coupon code Hall13.   ComboInk also has a 100% risk-free for one full year guarantee – the best guarantee I’ve found.  Their prices?  Pay $68.99 at Staples for a HP P1006 black printer cartridge or $27.99 at ComboInk.  You do the math…

I’ve used ComboInk exclusively for years with never a problem – for both laser and ink jet printers.
