u/briballdo Here are the baskets I'm using. I bought the Amazon returns for $16 each. I was also looking for a way to keep the seat on but carry groceries periodically. They're made for handlebars, but work in this application if the "hooks" are bent to fit under the seat without removal. I'm still working on the perfect bend angle and will probably add one thumb screw on each side (like I have under the seat) to make them more secure, but they're already working quite well. Watch for a future post/YouTube video once I work out the details. https://www.amazon.com/gp/product/B0185N3OA6
