Hi...I have never heard of JBF; however, we have a children's consignment sale in my city twice a year. They take just about everything...clothing, baby equipment (except for car seats and potty seats), toys, books, games, videos, decor, seasonal and holiday items etc. The list goes on. It must be like new, though. You register as a consignor and enter all of your items online. They print out the tags for you, you pick up at a designated location and you pin the tags (carefully, following their instructions) or tape them to your items. All consignors receive 60% automatically. If you work a three hour volunteer shift, you get 70%. If you work 20 volunteer hours, you get 80%. You are able to track your sales online as the sale progresses, which is really nice. The sale lasts one week, with several days prior to the opening reserved for consignors, grandparents and expectant parents to buy before the general public.
I have mostly Gap, Gymboree, Children's Place and Talbot's Kids stuff. I take very good care of it. The instructions from our sale are to price these types of brands at 30 to 40% of retail (especially if they are NWT). I usually price in the 40% area and my clothing sells. I also price equipment (Pack-n-Plays, high chair, bouncer seats etc.) at around 45%. I do not sell my items at half price and I don't donate all of them at the end (only things I really don't want back). Also, nothing can be priced less than $2.00, but items can be bundled (i.e. several onsies, books etc.).
Last sale, I had 60 items and got five back. I made $330. We have a sale that is currently going on. I had 79 items this time. I'll probably sell more next time. I have a ton of stuff here, but I just have a hard time parting with it. Sentimental value and memories, you know? Anyway, I've never had a problem with this consignment sale. I think you should try yours and see what happens. Good luck!
