Should you buy it or should you save your money?
If your treasured collections are in danger of engulfing your house, exercise a little impulse control before you think about adding that next tchotchke to the shelf!
First do a little research on that coveted item that's beckoning to you on eBay. Check the online reviews (perhaps ignoring the overly zealous ones, positive or negative). Then ask some friends whose opinions you value for their thoughts on your intended purchase.
When you head back to your computer armed with these new insights, you may discover that the desperately desired item isn't as amazing as you thought. Now you can put that money back in savings where it belongs!
