Is this a good deal?

Hank, you might want to look into Office Max and Office Depot. They both sell cartridges for your printer that once empty, you take back for a refill for $10. Not a bad deal, especially after I spent $60 on ONE cartridge for my HP printer at Sam's Club last time. It was an extended fill one, supposed to last twice as long as the regular. Does that mean they just fill the regular one halfway?
