Walmart offers the BV Bicycle Strap-On Saddle Bag / Seat Bag for $6.28. Opt for in-store pickup to dodge the $5.99 shipping charge. That's tied with our mention from three weeks ago and the lowest price we could find now by $1. It features 3M Scotchlite reflective trimming, Velcro straps, expandable medium and large saddle bags, and taillight hanger.
