Walmart offers the Spa Massage Lumbar Massager in Red, model no. H-4291-0 RD, for $5.93 plus $4.97 for shipping. That's $4 off and tied with last week's mention as the lowest price we could find. It features a contoured ergonomic design that purportedly supports and massages the lumbar area. It's requires two AA batteries (not included).
Running Warehouse offers the GU Roctane Energy Gel 8-Pack in Cherry Lime or Lemonade for $9.88. Coupon code "FB15D" cuts it to $8.40. With free shipping, that's the lowest total price we could find by $7. This energy gel purports to help reduce muscle damage, slow acid build-up, and increases carbohydrate converstion into energy.
