Yes they are very different. We have been bouncing around to different ones.
The real cheap Flea ($3per space) sales are all over the place. The vendors with tools seem to do pretty good there.
Another one the same driving distance in other direction of the $3 Flea, was different every time we went. The rent is $15 + Tax. Saw a tool guy sell out buy 11:00 Am one day.
We went to a market our fellow vendors told us about. Loved it Rent $15 per spot. Very busy market. Sold a ton of glass ware (the crap that want sell at a yard sale). Had priced right though. Only problem over 50 miles away,
one way. All said and done we made very little. And with gas prices climbing will have to have a van full of free stuff to make that one work.
.
We have one only 17 miles away. Rent $12, you only get one table and can not bring any in. Have heard that it is pretty good. Guess need to try it it is close. Have heard different things that kids clothes and books sell well there, and we certainly have plenty of that stuff. But this market is dead in the summer months.
Trial and error for the new kids on the block.
Movieman has great advice and knows his market well, ie. customers what sells ect.
Also the $3 shipping and handling fee has saved this new to ebay seller on common noobie mistakes.
