I can understand charging a premium price for plants like tomatoes and peppers that take so long to sprout and grow, but I can't get over seeing cucumber and squash plants for those premium prices! These kind of seeds germinate and grow so fast, I don't really understand why anyone buys plants. (But that's just my innate cheapness, I guess)
Seedcorn, if those tomatoes you spoke of were $2 for a 4-pack of small starts, that's not bad. When I was selling plants 15 years ago, we were getting $1.99 for a 6 pack, or .89 for a 3 or 4 pack from a different grower.
the mark-up is not what one would think in those starter plants, either.
Bonnie Plants puts them in on consignment. What doesn't sell, or what dies from neglect on the shelf, they give the store credit for. The profit on a pack from Bonnie is miniscule.
