For the past decade I have had an account with a local consignment shop. I drop off items, she sells them, and I get a percentage of the profit. It worked really well for me when I started. Then I was single, bought stylish clothes more frequently, and had lots of spare time. These days I shop for my clothing at second hand stores, and rarely at that. Spare time to lug items to the shop is near existent. And most of the stuff I want to get rid off is from my children -- and she does not sell baby/kid stuff. As a result, the money I generated from consignment sales has dropped to less than $10 per quarter. It is not worth the effort, or gas to drive there (about 5 miles away from my home).
My consignment drop off has been replaced by a donation to Savers, which gives me a coupon for 20% off my next purchase. The new routine is to fill up a bag of unwanted items, go to Savers, get coupon, shop, and save usually $6 - $12 per visit. I do this about once a month. It is a great way to keep moving unwanted items out of our home, save money on second hand purchases, reduce trips in the car, and support a non-profit.
If you have stylish clothing, accessories or furnishings that you spent a lot of money on in the past 2 or 3 years, consignment might make sense for you. For this frugal person, a 20 percent coupon off at Savers in exchange for a bag of donations makes more financial sense. Lesson, run the numbers. Question convention. An alternative route may save you time, money, and tread a little more lightly on mother Earth.
