The shops I deal with are mostly made up of hand tied jigs by guys like me. As far as ultra minnows, A lot of shops carry the Spro brand. Not a bad jig at all.
I think people go to these flea markets to look for deals. Don't rob yourself, but don't scare away people either lol. I was selling 2oz. minnows for $2.50 at a flea market and that is a good price for the buyer. 4 oz. minnows I was getting $3.00 for, both are about a buck to $1.25 cheaper than the shops get. Heck, I sell "6 packs" of 1/2 and 3/4 oz. jigs to some shops, and they sell them for 6 something a pack of 6. You just want to keep them a little cheaper than they can get at a shop.
At 1 oz., I would put $1.75 on them and I'll bet they sell fast at that. Powder coated and baked so they are chip resistant. Point out the 3d eyes also, and during conversation with them, mention how you could go cheaper with the eyes, but they don't hit the standards you are looking for.
Remember what I told you before, it seems like prices in NJ for tackle are a lot higher than De., so I think you will not have issues at $1.75. Remember to bring a lot of change, and $1 bills. Seems like everyone wants to buy something for $1.50 and hand you a 20 lol.
