I never realized how difficult shopping farmers markets without wheels was until I had a baby and started using the stroller to stow goods and hang bags from the handles. Life got a lot easier (in one way, anyway).
Use a sturdy, wheeled cart to make bulk purchasing and heavy objects (melons, winter squashes, citrus) easier to handle. This one can carry up to 100 pounds (that's a lot of tomatoes!) and folds down for easy storage once you're home (or do as I do and just keep it in the trunk).
