Today's grocery getter. Schwinn Varsity cost $5 at garage sale; modified with upright handlebars and handbrake controls from free junker bike. Trailer cost $10 at garage sale. Bungee cord supports underneath free from my gigantic road side collection. Plastic box is from my other trailer but a cardboard box would work as well.
Today's load bought at Walmart (12 mile R/T) was 12 two liter bottles of soda pop, 4 pounds of cheese and 2 weeks of cat food. Easy. Plenty of capacity for more too.
