Academy Sports offers five pairs of BCG Men's Mesh Basketball Shorts for $30 with free shipping. (Add five pairs to cart to see this price.) At $6 per pair, that's a savings of $10 and a very low price for men's active shorts in general. (Most stores charge at least $8 for a single pair of comparable shorts.) They're available in sizes S to 3XL.
Note: We saw five pairs of similar generic shorts for the same price yesterday, still active.
