Maybe I am an old meany, but I DON'T do consignment. I have gotten burned one too many times, the shop goes under, your product ends up missing, and no money has exchanged hands..... I have even had one lady pul my labels off of my soaps, and put hers on them, now this was a consignment deal, not wholesale!
I have gotten burned one too many times, i guess I feel now, that If they want my products in their shop, then they can work out a wholesale deal with me and at least after it's done, they are free to do as they will with the soaps, and I have gotten my money's worth out of them.
Now not every shop is like this, but just be careful, I have had good experiences and VERY bad ones..... Watch yourself, set some guide lines up front for both of you, remember you have to protect your products and the shop owner needs to protect their reputation. Have numbers already worked out on paper BEFORE you go into the shop for a meeting or to talk things over. Know the market that goes to that shop, you want a good market especially if your product is in there, so good rep. How much business does this shop do? is it worth it for you to allow those bars to 'sit' there for any length of time?
Maybe I am too analytical over it, but do your homework, and do a lot of homework before going that route.
