I also like shopping online. No lines, no going out, and easy to sift through products to find exactly what you're looking for at the best price.
So here's a happy marriage of the 2: Online consignment shopping. I just learned about a company called ThredUp, where you can sell your kids' clothes in good condition, and buy gently used clothing in good shape at steep discounts from the new, retail price. They often run special deals to make your shopping even sweeter. Right now, save 25% on your first order. If you have clothes to sell, order a free bag at their site and they'll send you a bag to ship your clothes in, at no cost. Check out their website for more details.
That sounds like my kind of bargain! Let me know what good deals you find!
