Tee,
I was not trying to be mean about where you shop or how you spend you money. I too am restricted with a fixed income . Shopping or going to a local nursery / greenhouse and supporting them is just one way that would build a relationship with them and is often beneficial to you in the long run. As the working relationship grows it too can become a friendship that helps both you and their business.
I have found that very often many times when my local growers have weak or scraggly plants, I often get those for next to nothing or for free most of the time . Even on veggie, flowers, trees, and just about any type of plants they have. So finding a good local supplier is a good thing as is a good working & friendship with them. You get the lil pots to grow seedlings in (free) plants and such (free) and help support local growers , and when it is wet and nasty you will always have a place to go visit to help out if you have formed a friendship with the owners for (free advise on your own plants that you are having trouble with ) so you and the local growers both win .
