Meritline again offers these Rhodium-Plated Superman Cufflinks for $3.99 with free shipping. That's tied with our March mention as the lowest total price we've seen for these cufflinks in over a year. (It's also $17 below the lowest total price we could find for a similar pair elsewhere.) These cufflinks measure about 1" x 0.6".
Of note, Meritline also offers the Superman Cufflinks in Red/Yellow for $9.99 with free shipping. That's the lowest total price we could find in this color by $21.
Expect these cufflinks to take two to three weeks to arrive.
