I posted this in commuting and utility, but you never know who's going to see it.
Long story short, my mom wants to fix up her old bike to haul groceries. We were at TJ Maxx, and I discovered something awesome. They have these light-weight, sturdy, foldaway, handle-laden, multi-colored bags that very easily could be turned into grocery panniers. I bought 3 black ones today, and I am just going to go figure how to attach them to my rack. Already sizing them up seems very promising.
$9.99 A PIECE!!!!
They also have a zipper pocket inside, and they come with 4 durable plastic strips to slide in the side for more stability.
I was astounded when I found these.
Here is what they look like. Note, these are what they look like, not the exact ones. Solid colors only.
If anyone has an awesome idea as to how to connect them to my rack, please post!
