most vendors will carry varieties suitable for container gardening. It is just a matter of reading the decriptions and choosing the appropriate variety of tomato, cucumber, eggplant etc that you wish to grow.

I've found varieties but can't find 1 vendor that carries all. I went order 4 pkg. from one vendor and they wanted $8+ for mailing.

Yes that is the reality of the situation. You won't find just one vendor that has everything you want and need.

But the seed packets store almost indefinitely so it is a one time expense.

Concur; It is difficult if not impossibel to find a single vendor who carries all the varieties one may want. While folks grow all types of regular size vegetables in containers by growing vertical ( trellis) small compact plants are desirable under many conditions. The two categories that need this are cucubits (squash melons and cucumbers) and solanums (tomatoes eggplants and peppers) Corn is not a great container plant but shorter >5 ft plants will work.
Several vendors carry Bush cucucumbers either pickling or slicers. There are lots of bush melons and even a few bush watermelons). Most summer squash wil work, even tho zucchini plants can get a bit large. The round types like Cueball, One Ball, Eight Ball, Lucky 8 are a bit more compact.. Winter squash, look for bush types. As for tomatoes, regular indeterminates pruned to a single or double leader and trellised work well. If not the there are lots of compact varieties available ranging from Patio to Arbason. As for eggplant Hansel and Gretel are popular but there are other compact varieties available. Peppers should not be a problem.
