I use a "Bike Burro" for shopping. The two-wheel, utility design lets it
double as a shopping cart. Unfortunately, I don't think it's made
anymore.
If your only going to use the trailer ON the bike, you might look into a
Beast Of Burden ("BOB"😉. This is a one wheel trailer that tracks behind
the bike better than two wheel designs. And because it leans with the
bike, there's no danger of trailer "flip-over".
I use this one for bike camping with my MTB, as it can be easily
removed, leaving my bike unencumbered with trailer attachments when I'm
on the trails.
