Since these days economizing is all the rage (whether through fashion or plain simple necessity), I've been sharing savings tips. Here's my latest favorite: get ink cartridges refilled. I go to Walgreens where black ink cartridges are filled for $10 and color ones for $15. This is almost a third of the price of a single new, brand-name cartridge and half the per unit price when you buy a multi-pack at a place like Costco. And they work just like a new one.
