Walmart offers the Stepsaver Instant Repairs Fast Patch 62-Piece Complete Kit for $3.41. Opt for in-store pickup to dodge the $5.99 shipping charge. That's the lowest price we could find by $17, although we saw it for slightly less last week. It comes with 62 paint ready self adhesive patches with steel center reinforcement.
These freebies are available to anyone with an internet connection, including both Amazon Prime members and nonmembers.
