I used these buckets obtained at Family Dollar a year or so ago. Less than $10.00 for the pair and I attached them with industrial grade zip ties. I have carried up to about 50 pounds in them with no trouble. I never did make a lid for them. I just used a plastic bag. I moved them back to solve the heel strike problem but I have smallish feet (size 9).
I have since replaced them with Wald folding baskets.
They are not near as handy nor do they carry as much but they do fold. I may go back to the buckets as they more convenient.
