Walmart offers the Salonpas Pain Relieving Patch 20-Pack for $3.88. Opt for in-store pickup to dodge the $5.99 shipping charge. That's the lowest price we could find by $2. (Most retailers charge at least $8.) Each patch measures approximately 2.8" x 1.8" and purportedly relieves pain for up to eight hours.
Laundry detergent is just as effective at removing spots as fancy stain removers — with one exception.
