I consigned in two stores, both were a 60/40 split. I sold my items slightly higher than I did on my online shop, so it worked out decently.
However, one store changed the split to 50/50 after two years. I hear this split is more typical.
The problem I encounterd was in order to make a profit, I needed to raise my prices again. The customers didn't like that, and my sales of course suffered. After about three months of selling at a 50/50 split I chose to stop consigning in that store.
Do what works best for you and if you don't want to raise your prices, then find another place to consign.
Personally, I like renting a space for a set price each month. Start off small and if it works for you, look into moving into a larger space. See if any shops around you offer rental vs a split. Good luck!!
