Walmart offers the Cap Barbell 14" Dumbbell Handle with Collars for $5.29. Opt for in-store pickup to avoid the $4.97 shipping charge. That's $11 off list, tied with our October mention, and the lowest price we could find for a single handle. (For further comparison, most merchants charge at least $18 for two of these handles.) It's made from one piece of solid steel and fits plates with a 1" hole.
