I, too, use booths at multi-dealer shops to sell a great deal of my stuff from storage units. I have a 6' x 8' booth at a shop next to a flea market that's open only on weekends and only takes cash. So there, I primarily put lower-priced stuff that's appropriate for either a flea market or is collectible. We've done better each month we've been there, as we've learned what does well from product and pricing perspectives. I have a big sale on handbags going on there (got these from a hoarder's unit ... over 70 brand new handbags) and they've been moving very well.
I've also just recently taken a set of shelves at an antiques/collectibles shop on a main drag in a more well-to-do area. I'm putting antiques and collectibles there. They do take credit cards and are open Thursday - Sunday. Not much action there, unfortunately. If business doesn't pick up there very soon, I'll exit immediately after Christmas.
We also have a shelf in a locked cabinet at this antiques shop so I can sell off jewelry items. The cost for the rental is so low, it will be much cheaper to sell items there than pay the final value fee for each on eBay.
Starting November 1st, we'll also begin selling furniture in a multi-dealer furniture warehouse connected to an antiques/collectible multi-dealer shop. We were on the wating list there for 4-5 months, I'm thinking low turnover indicates to me sellers must do pretty well there. I currently have my own storage unit to use as a staging area for furniture that I sell on craigslist. The monthly rent for 2 spots totaling almost 200 sq feet at the warehouse is lower than my rent for the 10 x 10 storage space! This shop is open Thursday - Sunday. It's near Brimfield, so it's also open every day Brimfield is going on.
Unlike many of the storage unit buyers we see here in Massachusetts, I like furniture a lot, so we have quite a bit. This new outlet should prove to be a huge boon.
BTW - the deal for all these spaces in the 3 shops is a flat monthly rent only. There is no fee based on sales made. The one exception is if a sale is made by credit card. Then, the shop keeps 5% of the sale cost.
With this variety of booths going now, there's not a lot we sell through other means. Basically, those items fall into 2 categories: 1) clothes - which we mostly sell on eBay using Buy it Now. For instance, I'm selling a lot of coats right now on eBay that we got in that hoarders unit with the handbags. 2) higher value or unknown value antiques/collectibles or items that appeal to niche collectors - again, these go on eBay primarily as auctions. Examples are pre-prohibition beer bottles and a 1979 Roland synthesizer.
